fixes issue about unknown type parameters for StdLibs::List

Functional interface wrappers should work now
Implementing a method with a signature differing from the actual one (e.g. when dealing with generics) now creates a proper bridge method
The Java Bytecde compiler used an incorrect method in checkCast
We now no longer use hardcoded 'accept's as method names but whatever the context tells us to.

Directly using the lambda where the functional interface is requested works.
The lambda class will then directly implement the functionalInterface and not use a wrapper class

- Save collapse state of the project browser tree

- Added support to have a native method both as operator and named method

- WIP on map files (used to link zencode to already compiled classes, and to define native methods)

- Fix default constructor not working properly
- Fix integration classes without exposed constructor being instantiable if they have a default (non-exposed) constructor
- Fix extern methods failing validation

- Simplified compilation process somewhat; removed CompilationUnit class and work more module-oriented instead

- Fixed a couple minor issues & inefficiencies
- Added horizontal scrollbar to IDE (incomplete!)

- Slightly improved the way modules are compiled

- Removed export access and added internal access support

- WIP on the module serializer

- Fixing function expressions not being properly linked to their functional interface

- Fix some problems when comparing a long with an int or ulong with uint
- Add signed-unsigned implicit array conversion (sbyte[] <-> byte[], short[] <-> ushort[], int[] <-> uint[], long[] <-> ulong[])
- Fix bug when copying multiple lines from the source editor
- Added string <-> byte[] conversion operations
- Fix unsigned arrays, use compact representations
- Added suffixes & custom suffixes
- Added 0x 0b 0o for hex, binary and octal notation

- Ranges now only have a single base type; from and to must be the same type
- Adjusted builtins and stdlib to use usize where applicable
- Moved building a SemanticModule from ParsedFile to the parser; reduces dependencies

- Rewrote iterator implementation

- Cleaned up unused code
- Refactored the JavaMethodInfo class to the shared JavaMethod one
- Use valueOf for boxing instead of the boxed type constructors
