Add DOAP RDFa support

[danbri]

The project.html page seems a good candidate for having DOAP markup added, since DOAP has relationship types etc for much of this info.

eg. see http://www.oss-watch.ac.uk/resources/doap.xml (most examples are rdf/xml not rdfa though)

Maybe DOAP needs an extra property, describing in text 'how to submit patches'?

From IRC,

tobyink: The one thing I'm not sure about is the svn:repository stuff. DOAP distinguishes between the browsable web front-end for a repo, and the "svn:", "git:", etc URLs. contributing.appspot.com doesn't seem to. I've assumed that the repo link is a browesable front-end, as it seems to be for all of the projects I've checked.
