Code review comment for lp:~mblayman/entertainer/translate-events

Matt,

I'm okay with the 2 goals of this branch.

This branch will lead me to change my callback variable name in "back_button" but there's no compatibility issues.
In "back_button" it's just handled on the Screen Class and wrapped in a "screen_back" method because I need that on every screen.

Bellow some minor comments :

Maybe a @property makes sense here instead of a method call to fit with the recent changes we've made.
The docstring needs a full stop.

Thanks,
