Minimal update for jQuery 1.9

I recreated my fork repo and now submitting the minimal needed to upgrade to jQuery 1.9. If this is accepted, I will reintegrate my other changes and do other PL's.

The diff seems crazy though. This is how it looks when I'm checking in:

This is how it looks after checkin.

Any ideas?
