Subject: [PATCH] keep undisplayed messages over redirects
When act_redirect is executed (post data was received and mode show is called)
all undisplayed messages (from calls to msg()) are saved in the session now.
These messages are then revived in inc/init.php. This makes sure no errors
that occured before the redirect are lost.
