Makes the hangers act more like multi-craft hangers rather than launch pads.
As of 1/22/2015 all it does is up the capacity to 2 crafts per hanger nothing else.
Plans make a large hanger and figure out how to make a pre menu to right click on hanger brings up what craft in hanger to equip and possibly shrink the craft on base screen to show multiple per hanger and make hangers cost more .
