* include/auth/mysql.php: Added get_user_id(). Removed field check on
create_user(). Allow to pass an structure to the functions and use
get_user_id() when needed.
* include/auth/ldap.php: Added get_user_id().
* include/functions_db.php: Improved get_group_users() to return real
users instead of tusuario_perfil values. Also a filter parameter was
added.
* include/functions_messages.php: Use get_user_id() on
create_message_group() because get_group_users() now returns
user structures. Style correction.
