PneumaticCraft: Repressurized

Added

• Added a new tube module: the Thermostat Module - thanks @johalun (coding) and @Ridanisaurus (texturing)
  • Measures the temperature of the block it's facing and converts to a redstone signal
  • Use a Redstone Module on the same colour channel to output the signal

Fixed

• Fixed Liquid Hopper not immediately updating comparator output level when fluid level changed
• Fixed Pneumatic Armor HUD stat panel forever-expanding if moved off the screen to the right
  • Also added a "Reset" button to the stat-moving GUI; retrieve stat panels which you've moved off-screen this way
• Some memory leak fixes and general improvements around handling and caching of air handlers capabilities - thanks @BlueAgent
