Code of conduct &c.

Here's an initial proposal for a code of conduct. This is [purloined](https://github.com/noisebridge/bureaucracy/blob/master/code-of-conduct/anti-harassment-policy.md) from another space which uses a modified version of the [Ada Initiative policy](http://adainitiative.org/what-we-do/events/ada-initiative-event-anti-harassment-policy/).

It's still a work in progress and there are [plenty of things to do](https://github.com/nortonimperiallabs/doocracy/issues?labels=community&state=open) to take us from an simple description of what not to do to a robust procedure for preventing and remediating poor behavior.
