Add ability to sort while queuing

Problem/Motivation

When running the orange-dam:queue-content-by-type command it would be helpful under certain circumstances to sort the result set. This can become very complicated very fast, and the Orange Logic API itself is tricky/hallucinatory when issuing sort flags.

Due to all this complexity, it might be better to initially limit the scope of this request to simply allow for passing a --sort option where the user can pass in an Orange Logic API sort type (sort6, "Oldest first", etc) and leave it at that.

The scenario I am trying to address is where the API limits a result set and I am unable to retrieve all the records. In order to queue a complete set, I would like to be able to queue half the set in one order, and then queue the other half sorted in the opposite order. Doing so should yield the complete set.

I have the changes already and they seem to work. Merge request incoming.
