Acceptance ui

Things to do:
Make handlebars helper to make roles uppercase and replace _ in copyright_holders with a space.
Debug why I am not getting a response on successful POST


The ending `(.*)` appears to be unnecessary, since the captured value is not being used and there's nothing after it.

It should probably be `/^users\/role-acceptance\/`, or `/^users\/role-acceptance\/(.+)` if you only want to match role-acceptance URLs that have a UUID at the end of the URL.
