Add note about serving public as web root

Laravel 3 docs had a little more specificity regarding the fact that only the public folder should be web accessible.  This change adds back this recommendation.  Inspired by this forum post: [http://forums.laravel.io/viewtopic.php?id=6751]
Removed mention of bundles
Small typo fix on configuration page
Update replacement .htaccess file

I updated the replacement .htaccess file with the recent changes in on the Laravel develop branch. I also generalised some rules and put them in the same sequence as the original version.
