Code of Conduct (for contributors)

[aamct2]

It would be good even in these early days of Textor to have a Code of Conduct for contributing to the project.

I'd recommend the Contributor Covenant. It's used by many open source projects, including Swift itself.

The one thing that would be needed is an email address where complaints could be sent, reviewed, and actioned. Otherwise the text is easy to copy into the repo. It's licensed under the Creative Commons Attribution 4.0 International Public License which requires attribution. The attribution is built into the Contributor Covenant text itself.
