Upgrade jQuery to 1.3.2 RFC

Upgrade to jQuery 1.3.2

From email sent by John Beppu <john.beppu@liblime.com>:

Currently, Koha uses jQuery 1.2.3. I would like to get it upgraded to the current release which is 1.3.2.

The significant changes that the 1.3 series brings can be found here:

http://docs.jquery.com/Release:jQuery_1.3

The 1.3 series brings many performance improvements and few new features, but a few things had to be deprecated along the way. The one that seems to cause the most problems for upgraders is the of the XPath attribute selector syntax, but luckily, it's also easy to fix.

Note by Joe Atzberger:

One important thing will be to check our plugins for 1.3 compatibility. Right now that seems to include:

• ajaxfileupload.js
• jquery.checkboxes.pack.js
• jquery.dimensions-min.js
• jquery.dropshadow-min.js
• jquery.hotkeys.js
• jquery.hoverIntent.minified.js
• jquery.tablesorter.min.js
• jquery.treeview.pack.js
• ui.tabs.js
