Day 0 bugfixes released. — Rattus Velocitas Steam update #1091311

- Fixed an issue where the Performance Ratio could swing wildly in one direction after a streak of failing to beat the EST time then a race where you did beat it. This was rather prominent on fresh saves, now fresh saves should have a more stable performance ratio. Saves from the release build of this game will eventually correct themselves as well. - Fixed an issue where the wrong slash character ('/' instead of '\') was used when displaying the Performance Ratio in the Player Profile - Adjusted the audio mix of the Ghost Missile (??? item) explosion to make it more distinguishable from a Shield shattering. - Fixed a bug where dropped Cheese didn't properly disable it's glow effect when picked up.
