QSML3 Alpha but it's slightly more realistic

This is an attempt of mine to take the QSML3 Alpha and make it look better, fix bugs, and get things up-to-date. Additionally, I made it a slight bit more realistic by forcing you to be at most 5 studs away from buttons to click them, forced first-person, jump/sprint stamina, and fall damage. Hey, there's a reason we paid money for those stairs, you lazy son of a- QSML3 Alpha is the work of TheWildDeveloper and the rest of the QSML3 Alpha development team of Quantum Science Inc.
