GitLab MRs now viewable in Tower

From @tobidobi:

There's news that might make an interesting post on your blog: today, we opened a Public Beta for a new major version of Tower - that supports GitLab "Merge Requests"! Finally having Merge Requests directly on their desktop computers should be a happy day for all GitLab users :-)

Tobias is going to write a short post and record a demo video of this new feature.
