Massive overhaul of headers: (part 1)
- Using forward declaration where possible
- Getting rid of includes
- Logger class moved to it's own source/header files
- "packing includes headers" GameSystem.h, GraphicsSystem.h and SDLStuff.h removed from project; files should forward declare/include only when needed
- linux.h removed; platforms will be handled in better way
- Various code tidying; Moving * and & to type names
- Moved some class methods from headers to source files
