Create a new pattern for Site Admin controllers:

1) They must all start with "admin_".  This pattern is not directly
   routable.

2) Their urls must be /admin/xxx.

3) The Admin_Controller will take the xxx and look for Admin_Xxx_Controller
   and will delegate to that admin controller, after doing security checks.

Moved the users and dashboard views into individual modules for now.

modules/user/controllers/admin_users.php
