Fix drag interaction between Leaflet map and jQuery UI Sortable list
The drag events of the jQuery UI Sortable list and Leaflet map were clashing. Trying to pan the map or move the bounding box rectangle was being interfered with by the Sortable list. Made the bounding box list non-sortable with additional condition in ParentView.
Also simplified the setup of jQuery UI widgets that get added to the jQuery object. This just needs to be done once in globals.js file, so removed jQuery UI imports from various files.
Removed sortable code from ParentStringView as it was doing nothing, not making the list sortable.
Added various IntelliJ run configurations
