Propagating upstream code of conduct changes

[This repository's code of conduct](https://github.com/rust-lang/rust/blob/master/CODE_OF_CONDUCT.md) is out of sync with the [rust-www code of conduct](https://github.com/rust-lang/rust-www/blob/master/en-US/conduct.md) due changes from rust-lang/prev.rust-lang.org#1062. This PR propagates those changes and brings the files back into sync.

 * Please be kind and courteous. There's no need to be mean or rude.
 * Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
 * Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works.
-* We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behaviour. We interpret the term "harassment" as including the definition in the <a href="http://citizencodeofconduct.org/">Citizen Code of Conduct</a>; if you have any lack of clarity about what might be included in that concept, please read their definition. In particular, we don't tolerate behavior that excludes people in socially marginalized groups.
