Subject: - put back config['session_length'] disappeared in r1493 but has
 always been used in the code (generates mysql errors on session garbage
 collector) - fix auto_login (die mysql when session timed out, but user has
 remember) - when a user reconnects from identification.php, the remember
 cookie was not deleted - fix all redirect warnings/errors (many changes -
 mainly in common.inc.php and user.inc.php) - reduced
 $conf['remember_me_length'] to 60 days, because now at each auto login the 60
 days countdown restarts
