 *  Clean URls for the Social Network
 *
 *  The idea is to access to the user info more easily:
 *  http://campus.chamilo.org/admin instead of
 *  http://campus.chamilo.org/main/social/profile.php?1
 *  To use this you should rename the htaccess to .htaccess and check your
 *  virtualhost configuration
 *
 *  More improvements will come in next versions of Chamilo maybe in the 1.8.8
