Minor patch: 0.728, MCCL fixes and Gemini Pulse force — Reentry - A Space Flight Simulator Steam update #583111

This patch fixes some issues with the FPS camera controller in MCCL, menu scaling, as well as some minor texture glitches and typos. You will now be able to normally walk up stairs, and the direction is not dependent on camera pitch. It's projected on the XZ plane. This is still a very simple FPS camera, and is intended as a check if it's needed or not. This update also makes changes to the Gemini Pulse mode, making each pulse last 20 ms, and a more realistic pulse force.
