A project is no longer considered as an order (result of discussion of august 2006 and joint design with Rafael). Orders should hold the "offer" hierarchiczal structure (with requirements, people, etc.) while projects are only a tool for reporting and structuring tasks, accounting, etc. I implemented a quick and dirty project_workflow to make project usable in a configuration with security. But the project module has still be be reviewed to integrate what is useful in the sev project and to integrate all the design of august 2006. Same for order.
