Release 0.1.7 — Xark Steam update #589264

1) Rebalanced weapon sharpness to be reasonable levels. You should have to really swing to get the sword swing to register. 2) Added item destruction. Cutting in game objects will slice them into pieces, and doing that to container objects will cause them to sometimes drop items. 3) Added a "swing" noise. Not 100% finished with this, but it's a key part of the sharpness balancing. If you can't hear the swinging noise, you won't deal damage. 4) Fixed NPC pathing issues. They can walk through doorways now, and should be less confused by objects. 5) Added boards which occasionally block doors. They can be cut up to get through.
