Bug 9572 - Opac info tooltip from branches is not well positioned

This patch removes the jQuery plugin previously used to display the
library information tooltip on opac-detail.pl and implements the
functionality using jQueryUI's tooltip widget. jQueryUI has been
upgraded to 1.9.2 in the process, which required some ammendments to
jQueryUI-related CSS.

To test, make sure at least one of your libraries has "OPAC info" stored
as part of its configuration. View a record in the OPAC which is owned
by that library. Hover over the library's name in the holdings table and
you should see a properly-positioned tooltip showing the "OPAC info."

Also test other jQueryUI-related functionality to confirm that the
upgrade didn't break anything: Tabs and datepickers should still work
correctly.
