Realistic Gasses

This mod is designed to be a foundation for future gas-based items in game.

The atomic weight of helium is 4.0026 Da and the atomic weight on nitrogen is 14.007 Da. Its relative (r) weight -10 so that value is set the game by this mod. By adding helium sacs to your pack you can now remove 10 units of weight per sac.

New gasses:

Hydrogen r-weight: -13

Oxygen r-weight: 2

Let me know in the comments if there are any other gasses I should consider including.
