Fix 'Follow Walls Stop For Others' incorrectly turning when bumping into someone while rounding a corner.

This movetype attempts to turn and then move forward a tile when it reaches a
corner, but the movement might fail if an npc/hero is there. In that case, next
tick it needs to know that it's already turned, and not try to turn again until
it completes that movement. I added a bool to NPCInst to track that.
