Loop on Petrine's quest

[basicals]

This needs a variable or a way to avoid a loop. Otherwise the replies are permanently available. Also, the script removes a RING16 (like in vanilla BG), but it shouldn't, since the removal of the ring is done by the unmoded reply "You be careful to stay out of trouble, kid.", which wraps up the quest.
