v1.3: Optimization & Freeze Fixes

Hello! Another update fixing a number of issues. Changelog:

• Fixed a freeze when hitting an antelope with an arrow, and it can't find a way to escape.
• Optimized drawing code, pathfinding, fog of war, and more - game should run a lot smoother (especially for large towns).
• Improved pathfinding so people will be OK with taking longer detours to get somewhere (fixing them being stuck previously)
• Max-detour distances of people are now the same for every action, making it more transparent.
• Skeletons will now also dash for 3 seconds after hitting them with an arrow, making them much harder to beat with just one villager.
• Made the windmill turning speed increase with the game speed properly.

Thanks again for helping make the game better!
