Simplify and restrict what users are able to do on Signon.

* 'Filter by Role' shows roles that are appropriate for the current user
* Only be able to administer users lower in the permission hierarchy
* Restrict the abilities of Admin and Organisation Admin users
* Can only grant users permissions for apps that the admin user can access
