Add support for Mercurial

[edvbld]

Hi all,

this patch adds skara.py which makes it quite a bit more convenient to use the Skara tools from Mercurial (hg). I also added --mercurial to git-pr and git-fork so they can be used with hg-git. There are still a few minor things to work out, for example hg pr create does not work yet and I need to do add some help texts, but it is a start.

Testing

• Manual testing with git token

Thanks,
Erik
