Make it easier to distinguish and edit queue topics and topic groups

[#1]

We have several global request queues that have 200+ queue topics due to very specific routing for each request type and region. These are really difficult to manage especially with multiple Topic Group levels and some Topic Groups that have the same name. If we could view the queue topics and topic groups on the same page in a structure that mimicked the actual queue setup, it would be so much easier to make changes.
