Problem when CDN is not available, and local copy of jQUery is used.

(Long time user, first time patcher. Not sure if I got the process right.)

Problem/Motivation

jQuery errors when using ctools modal forms. Modals not closing, generating jQuery error. Intermittent.

Proposed resolution

Script tag not closed correctly in jquery_update_xxx_backup(). Usually has no effect, but if the module is set to download jQuery from a CDN, and there is a connection problem, loading jQuery from a local backup will sometimes fail.

A patch is attached.
