Feature request: Pull button

[BrianEmilius]

As @johndbritton speaks of in this issue a button in the classroom client to pull repositories that are already cloned through the client would be a very nice feature.

This way, teachers wont have to clone all repositories again, when students have made changes to their assignments.

Is this issue going to be picked up?

I like that... this is not something we are looking at implementing right now, but I would happily help anyone looking to make it and would review a pull request.
