Ignore JVM segfault log files

This commit changes the following things inside the logging infrastructure:
- passing issuerClass, issuerOrigin and issuerMetadata is no longer required, relevant information is now being pulled from the stack
- split huge classes into multiple smaller ones
- separated "normal" and asynchronous logging classes
- simplified logging
- improved performance
- more detailed crash reporting
- regex-based filtering
- internal placeholders have been replaced with more lightweight method calls
- much more changes

-//     -------------------------------------- Log priority/type. In this case, we want to emit an informational message
-```
-
-Now, why do I need to supply so many arguments just for a simple "Hello World!"?
-It's simple: It describes the class issuing the log call.
-
-Here's an example:
-```java
-class ExampleClass() {
-    private @NotNull String string;
-    
-    public ExampleClass(@NotNull String string) {
-        this.string = string;
-    }
-    
-    public boolean checkForEscapes() {
-        Logger.diag(getClass(), "APPLICATION", string, "Checking for escapes");
-        return string.contains("\\");
-    }
-    
-    public boolean checkIfEmpty() {
-        Logger.diag(getClass(), "APPLICATION", string, "Checking if empty");
-        return string.isEmpty();
-    }
-}
-```
-
-Now that's nice and all, but it's annoying to pass three arguments describing your class to log methods
-and will – over time – make log messages unorganized and unmaintainable. That's not good. That's why
-the `LoggerInstance` class exists. It's purpose is to pass these to every log call you make. The only
-thing you need to do it to is to pass it some data about your class and it does the job for you.
-
-Here's an example of the code before, but with `LoggerInstance`:
-```java
-class ExampleClass() {
-    private @NotNull LoggerInstance logger;
-    private @NotNull String string;
-    
-    public ExampleClass(@NotNull String string) {
-        this.string = string;
-        logger = LoggerInstance.Builder()
-                .setClass(getClass())
-                .setOrigin("APPLICATION")  // If you intend on 'origin' being set to "APPLICATION", you can leave this out. This has just been included for completeness.
-                .setMetadata(string)       // Include the string we are doing stuff with as metadata
-                .build();
-    }
-    
-    public boolean checkForEscapes() {
-        logger.diag("Checking for escapes");
-        return string.contains("\\");
-    }
-    
-    public boolean checkIfEmpty() {
-        logger.diag("Checking if empty");
-        return string.isEmpty();
-    }
-}

-
-As you can see, it's much simpler. No need to pass that to every call now!

 ## What is it?
 The StarOpenSource Engine (or **sos!engine** for short) is a modular, extensible and easy to use Java game and application engine. \
-It is responsible for the logging infrastructure, creating and managing windows, playing audio and much more.
+It is responsible for printing log messages, providing utility methods, creating and managing windows, playing audio and much more.
 
-## Why another one?
-Yeah, it's true that there are many game engines and frameworks out there that intend to ease development of applications and games.
-I ([JeremyStarTM](https://git.staropensource.de/JeremyStarTM)) however have never seen an engine or framework, which can be extended easily, without having to fork it and without a complicated development setup.
-And I don't mean what you make within the bounds of the engine or framework, no, I mean the engine/framework itself.
+## There are `n` different game engines and application frameworks. Why another one?
+True, there are many game engines and application frameworks out there.
+I ([JeremyStarTM](https://git.staropensource.de/JeremyStarTM)) however have never seen an engine or framework be modular,
+extendable and easy to configure at the same time. Additionally, we intend on
+supporting applications and games. This means that you don't need to remember
+different APIs for your different projects and can instead focus on just one,
+perfecting your skills along the way.
+
+## Why Java?
+Java. Some say it's an awful language. We disagree, strongly.
+
+While it has some pitfalls, it's almost the embodiment of
+[OOP](https://en.wikipedia.org/wiki/Object-oriented_programming),
+providing the perfect base for creating a modular engine
+and framework like the sos!engine.
+
+Additionally, because of it's interpreted nature it's easy to
+modify the bytecode at runtime and perform various things
+to it before it's executed. This isn't really doable in other
+programming languages easily. Just see what Minecraft modders are doing
+to the game using the [Mixin](https://github.com/SpongePowered/Mixin)
+framework. It's a perfect example.
+
+Also important to note is Java's portability.
+Yes, it has it's constrains in some cases (like when accessing files),
+but these can be worked around easily (see our `FileAccess` class for an example).
+But generally, the code is portable. There's no need to cross-compile for
+different CPU architectures and operating systems. You don't have to deal with
+compilers and their 581^51 ways of configuring them. Just `javac` your source tree,
+pack your compiled bytecode into a `.jar` and you're good to go.
+
+Lastly, you can use and mix various languages and compile them to different things.
+Have Groovy code and want it to interact with Java code? That works!
+You want to use Ruby to create a game using the sos!engine?
+[You could do that](https://jruby.org). Want to compile your entire Java codebase
+to JavaScript for usable on the web? [TeaVM has you covered](https://teavm.org/).
+Want to compile your Java code into binaries for fast execution?
+[There exists GraalVM native-image](https://www.graalvm.org/latest/reference-manual/native-image/).
+Once you've written your Java code you can compile and interact with it however you like.
+As far as I know no language is as good in this aspect as Java.
+
+And these are the reasons as to why we use Java over C++, Rust or other languages for example.
+While yes, performance naturally suffers a bit, the JVM and computers in general have improved
+heavily in performance over the years. From the slow thing Java once was it's almost as fast as
+compiled code on modern machines. Most of the time you don't notice the difference. And if
+performance is your concern, use GraalVM native-image as described above (note: the StarOpenSource Engine
+does not yet support native-image, see [#3](https://git.staropensource.de/StarOpenSource/Engine/issues/3)). 
 
 ## Architecture of the engine
-The engine consists of the core engine (`base` dependency in your project) and various subsystems (`slf4j-compat`, `windowing`, etc.). \
- \
-The job of the base engine is to provide minimal classes and interfaces needed for an application.
-It contains among other things a default logger implementation, useful methods, event system and a placeholder system. \
- \
-Subsystems on the other hand usually handle complex tasks. They provide abstractions for libraries and operating system calls. \
-"But why are there so many of them?" you might ask. Good question! Subsystems are intended to [do one thing and do it well](https://en.wikipedia.org/wiki/Unix_philosophy).
+The engine is built as a modular system, containing the core engine (called `base`)
+and various different subsystems.
 
-## Available official subsystems
-Besides the `base` engine, there are two stable subsystem and three experimental subsystems.
+The job of the core engine is to provide a logging system, utility methods, ways
+for subsystems to seamlessly function and much more required for building applications.
+
+Subsystems on the other hand usually handle complex tasks.
+They usually provide abstractions for libraries or handle complicated tasks.
+"But why are there so many of them?" you might ask. Good question! Subsystems
+are intended to [do one thing and do it well](https://en.wikipedia.org/wiki/Unix_philosophy).
+This avoids unnecessary bloat, having too many dependencies in your project while reducing the
+size and memory footprint of your project.
+
+## Official subsystems
+Besides the `base` engine, there are two stable subsystem and two experimental subsystems.
+
+There may be other subsystems out there. Please note though that they are not maintained
+by the StarOpenSource Project directly and are not automatically updated with the engine.
 ### Stable
