CTextBox: add/modify methodes for screen handlings

Browse Source 
- split hasChanged() into hasChangedPos(), hasChangedDim()
- add return value bool to enableBackgroundPaint(), enableSaveScreen()
- add clearScreenBuffer(), for unified usage in destructor and functions
- add OnAfterRefresh() as a signal/slot handler, this allows to use
 external methodes as callbacks after painted text
