I should be able to delete a Custom Role

(User Story, Investigate , Priority: Medium, Test Status: No automated tests yet , Reported By Bad Link: Thing 3y285jl not found, )
Summary: Once a Role is created, there is currently no good way to remove it. That should be fixed.
In practice, this is a good deal of work to do safely, and isn't more than a mild inconvenience, so it's not terribly high priority.
