[development] changes in project publishing workflow

[Derek Wright]

after running into numerous problems with how we used to handle  
project workflow, i've changed some code in project.module and  
cvs.module, and killes has reconfigured drupal.org.  i've updated the  
handbook page about maintaining projects to reflect these (and other)  
changes: http://drupal.org/node/7765

the new workflow:

1) only users with a valid cvs account are allowed to create project  
nodes at all.  this removes a potentially confusing node type from  
the create content page for the vast majority of drupal.org users.

2) projects are no longer put into the moderation queue.  so long as  
the user has a cvs account (and belong to a role that has the  
"maintain projects" permission), they can create any projects they  
like, which are immediately published.  further edits of the project  
page no longer send the node back into moderation.

3) users with a cvs account can create new directories in the  
contributions repository, but can only tag directories that have a  
valid project node associated with them.  once tagged, the usual  
tarball generation stuff kicks in and does its thing.

i think this new method will remove a lot of project-related  
headaches and confusion.  let me know if anyone has any questions or  
suggestions for further improvements.

thanks!
