I removed 'previous' field from DIALOG_PLAYER struct and added list of
active (initialized) dialog players. New active dialog player is
obtained from this list when some dialog is shutdown.
I'm not sure, but perhaps we should sort list of active dialog players
in update_dialog, then next active dialog will be the last dialog
which was updated.
I've applied it to CVS (include/allegro.h and src/gui.c).
