Scott Nonnenberg 7ab20f09cc Fix focus issues with identity key send view
Tabbing right after entering the view would cause everythign to go crazy
as focus went back to the pane you were just on. This change both sets
the proper focus on load of that view (on the cancel button) and hides
other panes when they aren't active, only making them visible again when
they are once again the 'top' pane.
