Unique gas serialization for atmos (#1629)

* Add unique gas mixture serialization for atmos

* Refactor doAfterEventArgs

* Adds atmos commands

* Roundstard now has correct ratio of gases

* Fixed hashcode for gasmixture, better grid atmos serialization

* Airlocks create gas based on adjacent tiles now.

* Enables barotrauma component damage
