CoC Format Cleanup

added in a route for coc and cleaned up some formatting

[This](http://i.imgur.com/HkZlsnz.png) is what the page would look like.

how do y'all like the formatting of this? should the unacceptable behavior be at the top or bottom? do you think another format of this text would look better? anyone want to modify the text further?

Also, I put the CoC in the navbar for right now. We could put that under a dropdown for Community Docs (like a checklist for starting a user group and, at a later time, a conference). We could also put it in the footer for right now, as a lot of CoCs are located there.
