Conda Installer recipe

cc #416. As I said there, I'm not sure if you guys really want to maintain the installers for the whole dependency stack. It's possible that I was a little overzealous here -- there might be a couple packages that are included in the base conda repos [1] that aren't necessary here.

The `conda-recipe/moe/meta.yaml` can list version numbers on the dependencies, similar to the `requirements.txt` file. If no version is listed, the `conda install` resolver will just grab the latest.
