Patch by Samuel White <samuel_white@apple.com> on 2013-09-17
Reviewed by Chris Fleizach.

Source/WebCore:

No new tests, changed AXARIABusy attribute to AXElementBusy to uncouple the concept of busy with
the aria-busy attribute. This will allow us to expand on the definition of busy moving forward.
