v2.0.0 - a more solid codebase

If you actually used this project before you might've noticed a good few panics.
So far, I just ignored them as my rust skills weren't good enough yet to fix them properly and instead just used a docker restart policy.
This version (should) fix those issues, make the binary smaller and the server faster because the request line now isn't being parsed with regex anymore.

Full Changelog: v1.1.0...v2.0.0
Docker tags: 2, 2.0, 2.0.0
