Experimental Build 0.4.157

In this build we focused on creature AI, added graphics and game options, and adjusted some economy balancing.

• Fixed a bug causing creatures to hear the player everywhere, causing them to always track the player
  
• Fixed creature collision detection in the mines
  
• Fixed a bug causing creatures to still try to attack deceased players
  
• Updated functionality and content for settings screens both in-game and in main menu
  
• Rebalanced each of the different ingots to cost 2 ores from 3
  
• Rebalanced Plastic and Rubber recipes to provide 5 units each and only consume a total of 20 units of gas
  

NOTE: A more complete resource rebalance will happen in the near future so crafting/building recipes will better reflect the current mineral ore drop rates, this is simply a quick intermediate measure to ease the grind while that rebalance happens.
