- first part of CIntObject API clean-up.

- - mostly remove usage of (de)activateSomething functions
- - CIntObject's can be safely deleted in active state or without removing from parent first
- - Added CWindowObject to use as base of all windows (will be required for such features as shadows)

Report any crashes or glitches - it should not cause any issues apart from more console output. 

TODO:
- remove redundant (de)activate and show(All) calls
- decrease usage of blitAtLoc\printAtLoc methods
- switch all windows to new base
