- 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
