* undo_funcs.h: Removed setCursorParUndo to simplify things a bit.
Renamed setUndo family to recordUndo. Renamed FINISH to ATOMIC
which I think is a bit clearer. EDIT is gone, since it was
premature optimisation, and broken for mathed anyway.
* undo_funcs.C (performUndoOrRedo): Cleaned up and made it work
with cursor positioning in insets as well (math insets still do not
work, but that's a different story anyway.) It mysteriously
crashes sometimes with undo in the first paragraph, but I'm fairly
confident that this is a compiler bug.
