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.

Could you add a note in:
```
docs/contributing.rst
```
to bump these version numbers when we tag new MOE releases?  Also, are there any other steps needed to make your conda build system pick up the new changes?

lastly, if we need to bump versions of dependencies, is that as simple as editing the related yaml file?
