Contributing to the eclipse pdt project

Since lately several people ask “What does it take to get involved with the development of the Eclipse PDT?”; an official process should be created.

An initial draft is available at http://www.eclipse.org/pdt/documents/contributing.html. Our technical writer has checked the document (Thanks Keren!) but you are more than welcome to have additional comments as well (Bugzilla issue #240475).
