Adding a mercurial recipe.

Mercurial's only dependency is python so this is easy :)

For those of us who aren't git true believers.

This doesn't work with Python 3:

BUILD START: mercurial-2.7.0-py33_0
source tree in: /Users/aaronmeurer/anaconda3/conda-bld/work/mercurial-2.7
+ /Users/aaronmeurer/anaconda3/conda-bld/build_env/bin/python3 setup.py install
setup.py with python3 needs --c2to3 (experimental)
Command failed: /bin/bash -x -e /Users/aaronmeurer/Documents/Continuum/conda-recipes/mercurial/build.sh

Mercurial doesn't support Python 3: http://mercurial.selenic.com/wiki/SupportedPythonVersions

Hmm, OK. That makes mercurial no better than git in my view then. To me, the biggest advantage to having a VCS in Python would be that you could use it as a library, but the mercurial guys clearly don't have an eye to this use-case.

Anyway, thanks for the recipe. That will help, since some recipes themselves require hg to download the code.

@asmeurer I would say git is no better than hg - just a different way of looking at it I guess. IMHO the best aspect of a VCS written in python is that you can quickly and easily write extensions in python.
