Made the keynav stuff change to the solid background color the same as hovering over a button instead of the green outline.  I also fixed a typo in a tooltip with administration.  I also changed the way that the "sign out" link was being hit and moved it to be an onclick event instead so that you can also access it through keyboard nav.
