Bug 7747 - Replace YUI autocomplete with jQueryUI

Bug 7747 - Replace YUI autocomplete with jQueryUI

In order to facilitate a more painless process for converting
to jQueryUI I will submit separate patches for various "widgets,"
starting with Autocomplete.

This patch replaces all instances of YUI autocomplete with
a jQueryUI version. The patch includes an up-to-date version
of jQuery and jQueryUI libraries.

The patch also moves some markup in instances where it should
have been removed in favor of a different include.

To test, find the various autocomplete instances and confirm
that they are working:

 - Circulation search header autocomplete
 - Overdues patron attribute authorized value filter (must
   have patron attributes enabled, and a patron attribute
   defined which uses authorized values.
 - Authorities search plugin. Edit a MARC record and use
   an authorities plugin link to do a search for authority
   records.

Incomplete: There is a YUI autocomplete instance in a UNIMARC
plugin (unimarc_field_210c_bis.tt) which I couldn't figure out
how to test, even on a sandbox set up with UNIMARC. I could use
help with a follow-up.
