close all menus when tapping any button

I think I'm least likely to break something if I do this as explicitly
as possible rather than trying to figure out the right helper to put it
in once and for all. So just add some boilerplate to reset all state at
the start of each onpress1 handler. This seems like a good choice since
we aren't planning to add a lot more menus that would quadratically
explode the boilerplate.
