Message 226321 - Python tracker

I refactored the callbacks to eliminate duplication. I had to redo the menu addition to work with the new menu. This works great on Windows.  I am confident I did not change the logic, but it would still be good if someone tried font changing again on linux and mac.

I am not going to backport this to the 2.7 Demo version, as backporting has always been a nuisance and now the help and menu redesigns have also not been backported.
