[Feature request] Selecting push remote

[rzikm]

It has been some time since I used magit, but I think it allowed changing which remote the current branch gets pushed to. I just encountered a case where for some reason I want to push my branch to a remote I rarely use otherwise and I don't think there's a way to do that with gitu yet.

PS: I updated gitu today to see how it progressed and I must say it is improving very quickly! Love to see the progress rate.
