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

lib/mapObjects/CGPandoraBox.h
