* src/paragraph.h (public): new enum ChangeTracking,

indicating if ct is used in the current buffer.
	(cleanChanges): pass enum ChangeTracking.

        * src/paragraph_pimpl.C (cleanChanges): delete ct marks from
	paste content if ct is of in the buffer. Set content INSERTED
	if ct is on (bug 2207).

        * src/CutAndPaste.C (pasteSelectionHelper): pass information 
	about the current change tracking state to cleanChanges.

        * src/paragraph_pimpl.h (cleanChanges): pass enum ChangeTracking.

        * src/paragraph.C (cleanChanges): pass enum ChangeTracking.
