Point the repository URLs at their new owner

These moved from the Coffey-Labs org to jcoffey-dev, where they belong.
GitHub redirects a transferred repository, so nothing was broken by
leaving them -- but a source link that lands via a redirect is still
naming an owner that no longer holds the code, and the redirect only
lasts as long as nobody creates a repository of the same name in the
old place.

Only the seven repositories that actually moved are rewritten. Every
other Coffey-Labs URL is left alone: ihasmail, cairnobs and the rest
are still there.
