------- Additional Comments from chris fleizach <cfleizach at apple.com>
Beth, I've made these tab roles like we talked about
tab = AXRadioButton
tablist = AXTabGroup
tabpanel = AXGroup:AXTabPanel

I also mirrored the other Mac accessibility things relating to tabs, and tried
to follow ARIA spec.

I re-organized some code so that it would be easy to get all Elements from a
specific attribute. 

As a note, when i ran update-webkit-strings, it removed two accessibility
strings. i guess those are no longer used...
