Sandbox Mode Update — INTERSTELLAR PRIME Steam update #792897

Update Note: - added the ability to fly the capital ship - fix the graphical glitch in the hanger - fix collision in Module Assembly mode - fix furniture falling through the floor bug - fix ship module editing error - fix player position reset after loading bug - update Ship Assembly Drone UI - add furniture descriptions - NPC will be in the next update Annoying things to be aware of that is still a work in progress: * the module assembly is still extremely glitchy working with the Unity physics engine. We are finding ways to make it smoother. * Also along with Unity physics engine, when you fly in the ship in zero-G, be aware that you might get ejected out into space and can't get back in and might have to reload last saved. Trying to stay away from the walls helps. We are trying our best to balance between fixing known issues/polishing what we have and adding new features.
