[seam-dev] JIRA permissions update

[Pete Muir]

Max and I discovered a way to change the permission scheme for a  
project to correctly reflect the project members. The main change you  
will see is that:

* even if you are a member of the committers group, you no longer have  
committer privileges on the project - if I forgot to add you to the  
list of project committers, then please ping me
* the assignee list is now limited to the list of project committers :-)
* more people now have admin rights (ability to add releases and  
components)
