Description of problem:
If you click on a role, say Author, the bottom of the page shows a set of
checkboxes for every role & user in the system to 'add' to the role.
Clicking one of these & submitting 'Add Members' button has no effect.
cms.ui.role.name at top of role detail
cms.ui.search_prompt shows up above search prompt when you click the Add member
Fixed as of perforce change 29527. The harder part, the extra useless
checkboxes, was fixed in previous submit.
