"CONTRIBUTING" file in libtypes-uuid-perl

[Toby Inkster (TOBYINK)]

It's been brought to my attention that the licensing of this file has
been causing problems.

Firstly, CONTRIBUTING.pod is just a file on my own computer that is
used to generate CONTRIBUTING. As such, CONTRIBUTING is covered by the
same licence, as it is a derivative work.

Secondly, to avoid Debian having to bundle several kilobytes of legal
jargon, I'm happy to multi-licence the file under the same terms as the
rest of the libtypes-uuid-perl package, so that all files in the
package are similarly licensed.

A new version of the file can be found here:

    https://gist.github.com/tobyink/fbafb504f85c833c039f

I'm happy for this file to be used in the place of the old one, or for
the new licence terms to be applied to the old version of the file.

This goes for Types::UUID, and also any other Perl software that I've
written which includes the same file.

Please let me know if you have any questions.

regards

-Toby
