Added more gameplay related stuff: An answer during the dialog can now make the NPC aim for a new target anywhere on the map. He will then walk towards that target after the dialog has been ended. If the NPC is visible, this will happen using the normal calculations and animations. If he's not visible, it happens on a grid based approach where the NPC "jumps" from position to position until he reaches the target. If he comes into view again, he'll revert to normal mode, of course.
