Add Customizable Doors/Hatches

This would be incredibly useful. The door could be customized to be a regular door that opens regularly, a sliding door and other door things.

The hatch could be used as a space lock or something for astronauts to go through in space so they can exit and enter their craft.
The hatch could be customized to slide open, to do a spiral design and such.

You can customize the dimensions of the door/hatch, and when an astronaut clicks on the door;p/hatch it opens.
