[v4.1] JavaScript Server-side Physics + create-gmof-app

This release introduces the JavaScript version of the big feature-rich v4.0 update (that was previously TypeScript only)!

Also there is now an npx command to bootstrap a project with ease!
Just run npx create-gmof-app and it will automatically pull the files from the latest release!

I may have missed some bugs while testing, so if you spot some of those or just generally have any questions on the framework, please be sure to ask them in the Discord!

Have fun!
