Updated MetaStation.v39G.dmm to MetaStation.v39H.dmm
*Added the gravity generator, just above engineering. It's more vulnerable than on Box.
*Rearranged the incinerator room so the turbine computer works, also added a camera to monitor the vent.
*Added three tear gas grenades to the armory.
*Fixed some layout issues above the mining dock.
