ludic.npc (17.7): a person's fallback is a fact

Browse source 
A step round what is in the way, a target planned again after twenty seconds without progress, and a target given up are each pushed as NPC_F_STUCK (how, x, z), so the game can see where the way failed a person. The lake test expects one when a walker turns back from the water; the way test expects none when the world gives the way.
