redo version checks yet again

I'm starting to feel better after replacing 1 line with 20 and 2 new bits of global state. I'm now handling two scenarios more explicitly:

If I change Current_app within key_press, the corresponding text_input and key_release events go to the new app. If it's an editor it might insert the key, which is undesirable. Putting such handlers in key_release now feels overly clever, particularly since it took me forever to realize why I was getting stuck in an infinite loop.
Both 'run' and 'source' can hit the version check, so we need to be able to transition from the 'error' app to either. Which necessitates yet another global bit of state: Next_app.

  -- Another weird bit for a class of corner cases. E.g.:
  -- * I press ctrl+e, switch Current_app. I don't want the new app to receive
  --   text_input and key_release events.
  -- If I try to avoid text_input events by switching modes on key_release, I
  -- hit a new problem:
  -- * I press ctrl+e, am running an untested version, Current_app goes to
  --   'error', and immediately rolls back out of 'error' in the key_release
  --   event.
  -- Skip_rest_of_key_events is ugly, but feels cleaner than creating yet
  -- another possible value for Current_app.
  Skip_rest_of_key_events = nil
  -- Where to go from 'error' app.
  Next_app = nil
