Moved all object-related files to lib/mapObjects directory.
Renamed some classes to more readable names
Finally shattered CObjectHandler.cpp into tiny bits

- This file is now split into multiple smaller files in mapObjects
directory
- CObjectHandler itself now contains only core classes (Handler itself,
CGObject and interfaces)
- Cleaned up excessive #include's through whole project
Line endings are now unix-style
Cleanup:
- removed commented-out #includ'es
- renamed some files to match name of class
More cleanup:
- moved SoundBase.h to lib since it contains shared data
- added RMG info to object format. Note that data is not yet imported in
configs
- slightly updated API of object handlers
