More 'cleanup' for kyra.

Moved scene object drawing into its own class (see animator.h and .cpp) (this needs some more cleanup!)
Moved text displaying into its own class (see text.h and .cpp)
Also moved timer code to timers.cpp and button code to gui.cpp.
Also changed wrong (c) information in debugger.h and debugger.cpp
