Belt Item Models, Comet Catchers and the Fleet Formation

Improvements

• Every item that rides a belt has its own model now instead of the orange orb, and the dark ones like the Mind Extractor are brighter
• The Battery is a 2x1 plug-in like the Solar Panel, with one plug end. Batteries in older saves are cut to 2x1 and keep their connections
• New Game has one Tutorial box: on plays the Normal tutorial, off plays none
• The Normal tutorial now covers silica and AI circuits, Mass Drivers and the research station
• Tutorial hints that ask you to open the crafting panel say which key to press
• Railgun: its blast does 15% of the hit (was 30%), a hit pulls the enemies around the target onto the gun, and it does double damage to buildings
• The Railgun slug flies smoothly, the slug and its hit are orange, and the hit is 20% bigger
• The Railgun Slug is smaller on belts so it fits through turns, and you craft it in the Combat tab
• The orange Select Research border shows only when a tutorial step asks for research, and the tech's tile in the grid gets the border along with its tree node
• The "Too far away" hint sits just above Station Info
• New games start with the camera closer to your ship
• The Objectives header sits closer to its card
