Title: Make liquid gas textures more realistic

* Oxygen got a faint blue colour with high transparency
* Argon/Methane/Nitrogen are colourless with even higher transparency

I didn't touch the gaseous version of the textures, those are still bright white. Imho this could be explained by the fact that they are condensing at the tanks/pipes walls.
