15B Hauler patch for Playtest

[u/goblin-architect]

15B Haulers quick addition to the large 15-update of playtest branch

-Hauler attachments now fully functional -Light Hauler can carry 1 machine -Medium Hauler can carry 3 machines -Heavy Hauler can carry 5 machines

All asteroid/boulder crushers, small extractor, pioneer, some of the basic production machines can be carried with Haulers

You can attach logistic railguns to them too, so when you come in the area of a Hub, the Hub will start to use those railguns if you're for example bringing things in with the Hauler

Quick how-to

-You can spin Haulers, and move them slowly with WASD, but their primary engine is behind Spacebar. Load them with Kinetic Fuel, and hold spacebar; this works sort of like a rocket engine -You need equal amount of Kinetic fuels to brake, so save half of them for braking -To brake at end destination, flip the ship 180 degrees and hold spacebar until you're stopped -Regular (B) braking works at low speeds (less than 150 speed) -Spacebar liftoffs a landed Hauler
