Adding content admin users

• Ask each of the content-admin users to log in to the application at least once. Right now they will have read-only rights.

• Log in as an admin user, and navigate to /roles

• Select the content-admin role, and add each of the users to whom you wish to grant content-admin rights. These users should now be able to upload items and edit the items that they have uploaded (plus items transferred or proxied to them).

• Note that removing users from roles through the /roles interface is still (as of Hyrax 1.0.5) broken, and must be accomplished through the rails console.
