Title: Cleaner clean-up for JSONP callbacks

If the callback wasn't previously part of the global namespace, this patch ensures it's properly scrubbed.

The benefit is when you're inspecting the DOM in Firebug or similar, or if you feel a pressing need to traverse `window`, you won't see a stack of `jQuery01234567 : undefined` entries.

Something similar could also be beneficial for `jQuery.noConflict()` so that `'$' in window` evaluates to false. But one thing at a time :)
