[RFC] devel: script to calculate a list of authors.

[David Bremner <david@tethera.net>]

As an initial heuristic, report anyone with at least 15 lines of code
in the current source tree. Test corpora are excluded, although
probabably this doesn't change much about the list of authors
produced.

I realized both AUTHORS and debian/copyright are woefully out of
date. I think it makes sense to keep something like this in the repo,
both to ease updates and to document a policy. Presuambly 'author '
should be removed from the output, but I'm guessing Tomi will tear
this apart anyway ;).
