[jdf-dev] Review needed: Contributor guide

All, I've put http://www.jboss.org/jdf/stage/about/contributing/ up. It's a first draft of a unified contributor guide for jdf. I've included: * setting up ruby etc. for building stuff * contributing guidelines * release process The things I'm not sure of: * is the location right (about/contributing, appearing in the About menu)? * should we embed the relevant bits in examples/get-involved etc.? * is the level of the info right (conveying relevant info, but not very hand holding)? * is there content missing that we need. Thanks!
