Bug 11749 - Remove unused jQuery plugin jquery.hoverIntent.minified.js from the staff client

The jQuery plugin jquery.hoverIntent.minified.js is used only in the
OPAC, not the staff client. This patch removes it from the staff client.

To test, apply the patch and search for instances of "hoverIntent." Only
references in OPAC templates should be returned.
