Milestone 3 (v3.0.0)

There is nothing here yet.

Maybe add unit tests? I can help with that if you give me a headstart where you wanna put them and what you'd like to test

I do not really need them right now.

I want to start using ShapeEngine for my next game to find out how good/bad ShapeEngine works for making complex games right now. I already have been delayed for over a year ^^

After all I want to know if it works for production and not just on paper or simple examples.

I renamed the milestone to 3.0 because the 1.1 release became so big that I decided it will be the 2.0 release instead.
