API REVIEW request for RT17668 Disable/enable tabs in a TabPane

Without having spoken to Kinsley  (I walked in the door 10 minutes ago 
from JavaOne Japan / vacation), my gut feeling is that 'disable' should 
make the tab unable to be interacted with by the user, but it should 
still be selectable programatically (with the tab having the required 
disable look). I don't think the Tab content should be disabled when the 
Tab is however.

I don't think it is necessary to include the selectable property, but I 
might be missing something.
