 * Views Bulk Operations doesn't respect Role Delegation's permissions in the "Modify user roles"
 * action and will offer all roles as options to add or remove from the users being edited. This form
 * alter fixed that by checking which roles the user had permissions to assign and altering the options
 * in the select element.

 * This is no longer needed since I can just use the "Delegate roles" action provided by Role Delegation.
 * I didn't realise that was there!
