Revision 1082916

Update - Update the jQuery library to version 1.5.1. A few changes were necessary for this step. I updated the jQuery flot library to the current release, because the old one doesn't work with the new jQuery version, i also updated the jsTree Plugin to make it work with the new jQuery Version. 

Note in jQuery 1.5 the implementation of the ajax function has been changed.
