Description

Only show the focus ring when a user has focused an element with the keyboard.

Goals / Use Cases

don't show a focus ring when clicking on the selected tab

Non Goals

don't show focus rings on other elements; this is more difficult as the existing focus code doesn't always update its 'focus by mouse/key' state properly and there are numerous additional cases to handle

Design

for Firefox 3.1, just add an attribute on a tab which indicates that it was focused by the mouse. For trunk, we should use a css pseudoclass to select specific focus behaviours.
