A first-use guide in the Cradle, and clearer thrusters

Shattered Rift now has a first-use campaign guide that appears in the Cradle. Its prompts switch between keyboard and gamepad, it remembers seven milestones as you reach them, and you can turn it off in Options. We also fixed a glare problem in the chase camera, where flame particles were piling up behind the ship. The thruster ports and rear hull panels now show clearly. Broader flight, controller and art review is still ongoing.
