new project: sphinxcontrib-paverutils

Kevin Dangoor’s Paver includes basic integration for Sphinx, the
excellent document production toolkit from Georg Brandl. As I have
written before, however, the default integration didn’t quite meet my
needs for producing different forms of output from the same inputs.

Georg has opened the sphinxcontrib repository on BitBucket for
developers who want to collaborate on providing unofficial extensions to
Sphinx, so I decided to go ahead and package up the alternate
integration I use and release it in case someone else finds it helpful.
The result is sphinxcontrib.paverutils.
