Implemented the listing of all the roles in for a specific group. Removed a TODO about removing the tolist assignment in soc/views/models/host.py because this list is now obsolete. Added a TODO to change the redirect of the member listing once the manage page is done. Patch by: Lennard de Rijk Reviewed by: to-be-reviewed
