DOCBOOK: Added proposals to DocBook SourceForge

Keeping track of proposals entirely in email seemed like a poor organizational
strategy :-) so I've added a 'Proposals' document area to the DocBook project
at SourceForge:

  http://sourceforge.net/docman/?group_id=21935

                                        Be seeing you,
                                          norm
