Source code reorganization. No functionality changes.
- Moved parts of UnCore.cpp to UnCoreCompression.cpp, UnCoreSerialize.cpp and GameDatabase.cpp
- Moved win32 typedefs from CoreGL.h to Win32Types.h
- UI/BaseDialog.h now correctly compiled without "RENDERING=1" define (previously it required CoreGL.h to be included where Windows was declared)
- All win32 libraries are now include thorough #pragma comment(lib, ...)
- Reduced size of pkgtool (cleaned up its Build.h)
- Added simple UITest project
