An optimization update a lot of you asked for :)

Changes

• Improved physics performance on large ships. The game should now support much larger builds without breaking.
• Reduced loading times on complex scenes.
• Reduced the stuttering occurring when building.
• Improved performance when there are many docking doors.
• Fixed the colliders for corner pieces. There should no longer be "ghost" detection when aiming near corners.
• Fixed the save list not displaying properly on the first game launch.
