Two grids connected will no longer attempt to go to space, do note multiple grids with vac cells and multiple sub-grids between themselves may still have odd lift properties

Update 1
Added Config file. It is now possible to change the amount of lift per cell, you'll find the config file in the world save's storage folder

Improved lift logic, Vac cells will now account for grids on Magnetic locks such and connectors and landing gear, Do note the bug with cells across multiple grids is still not fixed
