o Tweaked the wallwalk:
- The wallwalk scans only fire upwards in the NE, SE, SW, and NW directions, not down and not in the player's view direction.
- The origin displacelemt does not fire if the player has a floor 10 units underneeth him/her, so that skulks on the ground won't snap to the wall.
- If the player's view is directed roughly 45 degrees out from the current surface normal, the origin displacement is disabled, allowing skulks to fall off walls by simply looking outwards and moving away from the wall. Note that this makes it harder to climb around edges.
