Housekeeping

I'd like to unblock the npm release (#84) so I'll land this shortly pending any objections. We can always revert problematic changes until we do the final release but I'd like to at least release an alpha for people to test.

LGTM. Copying the jQuery.type code looks like the easiest way to deal with the way it's being used here, otherwise there's a lot of rewriting to do and given the plugin's age it's probably not time well spent.

@dmethvin thanks for a quick review! I've submitted one more fix (#121) and I'd like to release an alpha with them all today or tomorrow.

The QUnit update was kept on master (for a future 3.0.0) but it was reverted on 2.x-stable to maintain IE <9 support there.
