Implementation of Video Queue (show queue, add and remove entries)

I chose to create a resource under user to allow access to queues using routes that include the user ID.  But I also kept the my_queue route at root which is sent to the same controller.  The controller is tolerant of an omitted user_id and assumes it to mean the current logged in user.  Note that this complicated my test writing so I had to write extra tests for various cases of user_id supplied and omitted.

Technically this spec is wrong. Based on the description you should be verifying that it redirects to `root_path`. What if you changed your root_path? The spec would probably still pass but should fail in that scenario.
