Remove the app.Draw() gorountine

Prefer to have widgets force a draw when their data changes. This should
reduce draws (unless the user has a module installed that updates >=
1/sec, the old draw default).

This should also remove a source of some of the race conditions that
users were experiencing (though not all, there are still many).
