Rename to FocusObserver (or something other than Delegate, since it's not a
delegate).

FocusDelegate isn't a good name. Renamed to the verbose to the more verbose but
specific FocusDuringUnminimizeWindowObserver.

Wow, this file looks like it was a lot of work to convert. It'll be a great
example for future conversions.

[sky, 2016/10/06 17:57:07]

Tedious, but mostly mechanical changes. Hopefully future ones go smoother as
AshTest gets more functionality.
