Add a CONTRIBUTING.md file.

This file tells would-be contributors how to make our lives as
maintainers easier. It's very much a first draft and I welcome your
suggestions and contributions.

I have submitted this pull request from the primary repo into itself so
that other maintainers may add stuff directly.

I purposefully made it much larger than most CONTRIBUTING files due to
the (ideally) large number of people contributing who are not as
familiar with the tools as we are. You might even note my standing offer
to help *anyone* who wants to contribute do so.
Fix erroneous link.
