Prefer to have widgets force a draw when their data changes. This should
reduce draws (unless the user has a module installed that updates >=
1/sec, the old draw default).
This should also remove a source of some of the race conditions that
users were experiencing (though not all, there are still many).
* Add ability to select and open reviews
* Add more keyboard shortcuts
* Fix issue - focus shortcut letter wasn't displayed on the title area
* Cleanup some code
When no widget has focus, press the letter key to focus on the widget
assigned to that letter.
Example:
GitHub (d)
Press "d" to focus on the GitHub widget.
