Title: generalize event handling from CustomScreen

Several things happened here:
- start_screen now gets a lua object directly, not a name to load
- lua gets a couple of notify_* methods, with a stub callback registration api which is used in title_screen now
- CustomScreen forwards its on_display to the passed lua object reference
