CComponents: rework kill()

Browse Source 
There was some problems with restore, hide, clean and save background of item parts,
seen in detailsline. kill() worked not really clean.
kill() works now as virtual member and uses paintBackgroundBoxRel().

In consequence of which:
-unnecessary members in subclasses removed.
-add some comments
