pqSMTKNewResourceBehavior: accommodate multiple create ops per rsrc

pqSMTKNewResourceBehavior originally created a menu with the resource name as the clickable action that launches a create operation for that resource. When more than one create operation was registered for a resource, the resource name would appear multiple times without an explanation for each operation. This update handles the case where there are multiple create operations for a single resource by displaying the resource name as a menu containing the operations within it.
