[DRAFT] MEX Spacely

This XS-core was an experiment to have not 2 voxels as a centre line, but only 1 voxel.
The first edition had an interior with bed, a sink, seats and a dining table. Only 1 S container cargo.

For this new sales version I have smoothend out some voxels, removed lots of interior and added an S-container As well as 4 xs container.
Also added vertical directional space thrusters. The entrance has been moved from a hatch to an elevator.
The airbrakes are still inside but there is plenty of room to move them to the outside
