- Moved the main index to a sub folder /webroot along with all other public data (CSS,JS, IMAGES).
- Created an .htaccess to forward all requests except those for files in the webroot folder to the index.php.
- You must now setup your server to point to /path/to/site/webroot as the root directory.
- You must now pass a server variable _HTROOT_ equal to /path/to/site or the root folder containing your application and core folders.
- facebook_model->login() now returns the login array.  Probably can remove the session write as it's not really writing anything session important.
