Apps are now single-inheritance because micropython doesn't support
multiple inheritance initialisers (plus it's a bit simpler for app
writers).
All apps (except ones that need to synchronously poll for response in
a low tech fashion, like otaupdate) now use callbacks for button press
events, and own a Buttons object (self.buttons) set up in the App
constructor. Apps which require USB or WiFi need to set
get_scheduler().sleep_enabled = False to prevent lightsleep from being
entered.
