Fix focus issues with hotkeys

Since making use of keypress in addition to keydown, hotkeys did not
work in certain scenarios, including clicking on the feed tree expanders
or empty spaces of the toolbar.

This issue is caused by dijit.Tree and dijit.Toolbar implementing the
_KeyNavMixin, which explicitly stops propagation of keypress events.

This change contains two main fixes plus a smaller hotfix:
1. It overrides _onContainerKeydown and _onContainerKeypress for
   fox.FeedTree (which inherits from dijit.Tree).
2. It adds fox.Toolbar, which overrides _onContainerKeydown,
   _onContainerKeypress and focus. This fixes hotkeys being swallowed
   and the first focusable child receiving focus when clicking on an
   empty space of the toolbar.
3. It adds the same handling of keydown and keypress to the prefs hotkey
   handler as is done in the main hotkey handler.
