Update loader & misc

- [src/misc.gd] Add get_sign() function
- [src/misc.gd] Add get_sign_float() function
- [src/loader.gd] Change variable order (that makes a bit more sense)
- [src/loader.gd] Fix path resolution
- [src/loader.gd] Prefix all logger.error() calls in initialize() with "await" to prevent Godot debugger errors
