Description of problem:
Main issue: 

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.

Globalization issues:
cms.ui.role.name at top of role detail
cms.ui.search_prompt shows up above search prompt when you click the Add member
link.
