interestingly, I also discovered that GitHub will properly resolve links
that are relative to the root path (e.g. "/doc/foo")... it properly
rewrites these links to reference the named file relative to the
repository root.
also add a /doc/contributing.md file. This will never be served from
the website, since we have a redirect handler in place, but is added so
that we don't have broken links when browsing the docs on GitHub.

this is now needed to have camweb wrap the file in the site template
rather than just serving it raw.
