separator role on button

[stevefaulkner]

Gerard Cohen asked me why role=separator is not allowed on a button element. From reading the definition in the aria spec, i don't see a reason not to allow.

you wizened souls may think otherwise?

[scottaohara]

naw, that seems quite reasonable esp. since it can represent an interactive control that a button could reasonably serve as a base for.

[scottaohara]

and boosh. easy PRs are easy. gotta inform the checkers now / get some implementation commitments to acknowledge this change, and then it can be merged if good to go
