Allow tito to perform a github release

[jmrodri]

We've been doing Github releases by hand which I find weird having used tito for all of my other projects. We do a semver tag ie. 1.2.0, then a changelog to put into the release, it seems like it would fit into tito.

@dgoodwin what do you think?

@jmrodri, I like this idea too, because it is exactly what I do for my project. Release (from Makefile, so it prints me a link for github page with the tag) and copy-paste changelog there.

I think, that it should be possible to code it.

What do you think @dgoodwin? I would offer myself to implement it, as I have a personal interest in it.

I would love to have this as well. I am doing Mock github release by hand too.

[dgoodwin]

Sounds good to me.

[FrostyX]

@dgoodwin cool, you can assign me to it then.

I think I need to add you as collaborator to be able too, request sent.
