jQuery Suggestions!

I accidentally pushed these changes to the feature branch - I hard reset things and pushed up to my own branch instead, so hopefully that all worked.

I redid the suggestions code to use jQuery so we don't have to deal with gross xmlHttpRequest stuff by hand. Right now, the code appends bare result links to the form, but that's really a proof of concept - plenty of styling can be done there, and we get to avoid iframes.

I also updated jQuery from 1.4.4 to 1.9.1, and set $ on the window because Drupal compatibility mode is annoying as shit.
