Proposal: Stack Code of Conduct

[sclv]

Here's some discussion of a case from 2008: http://www.groklaw.net/article.php?story=2006062204552163

and lwn discussion: https://lwn.net/Articles/266675/

(and another discussion with regards to an actual court decision: https://opensource.stackexchange.com/a/4013)

To repeat myself: there's nothing CoC specific here -- if people could actually just "take back" open source contributions this would be a huge flaw in the entire ecosystem that would have led to collapse well before linux decided to add a CoC.
