- 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
