[added] disabled prop to rootClose

[jquense]

Allow the child to remain mounted while conditionally disabling the behavior

I meant to ask – do you remember why we (I) did this instead of checking something like domHelpers.contains(ReactDOM.findDOMNode(this), event.target) or something?

[jquense]

I don't remember hmm...this approach should be more performant, since its not doing a contains, tho contains is super fast actually. I don't know :P

It'd also skip the bizarre wrapper.

probably worth revisiting
