Subject: [PATCH] git-gui: Allow vi keys to scroll the diff/blame regions

Users who are used to vi and recent versions of gitk may want
to scroll the diff region using vi style keybindings.  Since
these aren't bound to anything else and that widget does not
accept focus for data input, we can easily support that too.
