Update notes for 2, 1, 6

This update includes:

• Falling rocks are less dangerous: fixed a case of falling rocks hitting the miner when they shouldn't.
  
• Buying a new lamp now comes with a full tank of fuel.
  
• Added a drill fuel tank bar to the HUD.
  
• Added drill fuel, light fuel and bag storage indicator bars to the shop screen.
  
• Lower value gems (citrine and rhodolite) are now much quicker to dig.
  
• Falling ladders now land on top of lifts, rather than falling to the bottom.
  
• Reduced the "stickiness" of lift platforms. Pressing up or down away from a platform no longer teleports the miner back to the lift.
  
• Fixed the top of lifts being covered by dirt from a cave-in.
  
• Fixed parachutes not closing when the miner lands on a lift platform.
  

Thanks to everyone who gave us feedback on these issues!
Happy digging.
