mysql create user function

This patch adds the missing function createuser in the mysql auth module.
Some new SQL statements have to be defined so that it works:
$conf['auth']['mysql']['getgroupid']   to get the ID of a given group
$conf['auth']['mysql']['adduser']      to add a user to the database
$conf['auth']['mysql']['addusergroup'] to let the user join a given group
