large filesystem update. Filesysytem is now fully functional, everything should work.

- completely replaced CLodHandler, removed bitmaph and spriteh
- replaced CLodStream in favour of CCompressedStream (2 new files)
- renamed CResourceLoaderFactory and ResourceIndetifier to shorter names
NOTES:
- campaign loading is currently broken. Will fix.
- I am going to remove several unused files in several days (e.g. LodHandler)
