Update 0.8.82

This is the last minor update before focusing on the new story mission.

• Elysium 2 - The level was not designed to be a maze, so moving around the level has been simplified, with more obvious direct cuts between blocks.
  
• Sector shields now turn white when damaged and restored.
  
• Calling a shop now has no phrase delay.
  
• An enemy that raises an alarm now provokes nearby enemies to react to the player as well.
  
• Regular enemy machinegun turrets now shoot more precisely.
