This commit does several things.
I am assigning functionality to the assign button. I added a variable in the queue controller scope, currentUser to store the username for assigning SRs.
It scrolls the screen back to the top when selecting an SR.
I moved the APIServer variable out of hardcoded values in the controller.
I set filterSubscribedQueues to default to true.
Upon selecting an SR, the screen scrolls to the top.
I also added more logging to assignSR and commented out the actual assigning part of the code so I can test.
This is where I'm going to store the apiURI and nodeURI variables.
