their results, as opposed to having them return their view back
upstream. This is a little more code in every controller, but it's
much less magical and more consistent.
Look up the active_theme and active_admin_theme inside the view
itself, no need to do that in the controllers. This makes view
initialization easier in the 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.
o Copy all the assets from default to default_admin so that they're
totally separate
o Get rid of $item_theme
o Rename list_users.html.php to users.html.php
o use __call in admin controller to allow us to load any admin page
