Set accepts_tab to False for the two Address fields

This is the simplest solution, since I can't figure out how to set the tabbing
order in Glade. Turn off the accepts_tab property (there's very rarely any need
for a tab in a street address) and the focus moves between input fields with
the tab key. Not quite in the order expected, but it at least it does.
