Company faces

Recently started trying out [company](http://company-mode.github.io/) for doing auto completions in emacs. The default color scheme is hideous with moe-theme, so I've made a few additions to the face definitions to tone it down a little.

Default on dark:
![moe-theme-default-company](https://cloud.githubusercontent.com/assets/1134611/3315008/bdb010d6-f6f6-11e3-8668-08e3eef76549.png)

Default on light:

New additions on dark:

I'm not personally sure the color choices I've made are the best (I'm not an artist, you make much better color choices than I do, and I would love it if you would tweak the choices for the faces), but it at least makes company useable on moe-dark without feeling like I'm gouging my eyes out.
