Add a few elements to the db.common.attributes definition:
 - vendorurl
 - sponsor
 - sponsorurl
 - contrib

This will allow attribution for sponsored or contributed
work on FreeBSD in the release notes.

This is a prerequisite to additional upcoming changes.

While here, modify docbook.css to recognize a new 'contrib'
<span> class.

Also, set FreeBSD=%H on docbook50.dtd to allow the commit
to go through.
