Version 1.3.4
  Changes:
    - Removed liquid gases, cryogenics and liquid heater/gas cooler (useless)
	- Removed gas barrels
	- Removed solid fuel from hydrogen
	- Order fixes (but won't work...)
  Balancing:
    - Changed crude oil desulphurization, 1 sulfur is now gained from 20 (5%) crude oil
  Other:
    - Changed icons for barrels (including crude oil barrel)
---------------------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------------------
Version 1.3.2
  Features:
	- Added liquid sulfur dioxide
	- Added sulfur dioxide and sulfur trioxide barrel
  Changes:
	- Removed naphtha and associated recipes and items temporarily, beacuse naphtha is still useless (won't implement useless stuff :P)
	- Cryogenics also needs fluid handling
  Other:
	- New petroleum icons are disabled by default
---------------------------------------------------------------------------------------------------
Version 1.3.1
  Features:
	- Added cryogenics research
	- Added oxygen, hydrogen and nitrogen barrel
  Changes:
	- Oxygen production research no longer effects oxygen production from atmosphere
  Balancing:
	- Sulfur processing recipes need/produce 10 times as many as before
---------------------------------------------------------------------------------------------------
Version 1.3.0
  Features:
	- Added liquid oxygen
	- Added liquid hydrogen
	- Added nitrogen and liquid nitrogen
	- Added liquid heater and gas cooler
	- Ratio between gas volume and liquid volume is 10:1
  Balancing:
	- Gas recipes need and produce more gas (because gases have more volume per unit than liquids)
---------------------------------------------------------------------------------------------------
Version 1.2.1
  Features:
	- Added disulfuric acid barrel
	- Added solid fuel from naphtha recipe
  Changes:
	- New orders for barrels
	- Naphtha cracking recipe needs hydrogen
  Balancing:
	- Crude oil has realistic heat capacity, temperature and speed
