Refresh is used in the python domain to refresh the display with the current
design. If something has changed, board connectivity likely needs
rebuilding.
If using GAL canvas, update its display db.



I am still looking at board_commit. This patch is to help those who already
have working python code. Also, as I mentioned in my board_commit thread,
<https://lists.launchpad.net/kicad-developers/msg32063.html> there will be
some scripts for which undo functionality is not needed.

also, in the same thread, some suggestions were made on getting GAL to
redraw. They all seem to require doing something before changes begin and
then calling something else. This patch enables the catch all of "just
rebuild whatever needs to be rebuilt"

for my personal reference: this is my fifth patch.
