Subject: Fixed $USER and $SESSION to be pointers to the real $_SESSION
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=08c17336a78449cbb63daafe5296acd06cb81c43;p=moodle.git

Fixed $USER and $SESSION to be pointers to the real $_SESSION
variables, so there's no longer a need for save_session  (thanks,Petri)
