Fix text selection in sortable forms by initializing the drag-sort only when the handle is hovered - thus ensuring the jquery plugin will not stop selection of text in fields; also removed unused jquery.sortable plugin as we're using the jquery UI plugin
Fix HTML5 elements in IE7/8 not being recognised so nothing works; fix js errors when editing notes and creating from the linker;
