Early look at the User/Auth module refactoring. It will look for a driver based on the contents of the user/config/user.php file. And load that driver based on the User_Driver interface. There is a default User_Gallery_Driver class that will provide the actual interface implementation. Replacing this driver will allow a completely different user and authentication implementation to be used... hopefully will reduce issues with embedding and other user management systems. Removed from unit tests so they will still run.
