Make the core have a long form instead of a square only

[tuktuk]

At the moment all the big ships come out as big squares, i personally want to build a long ship.

So i suggest to enable us to choose a long format when deploying a core, so we can build longer ships that are not so square.

 

It would also be nice if we could move the core to the side of the square instead of sitting the middle, this will enable other types of ship builds such as a cockpit in the back with the front part splitting in two.
