v2.0.0-beta1

This is the second preview for CubeKit 2.0.
I've bumped the channel from alpha to beta because of the massive milestone we've made in the tooling and infrastructure of CubeKit - which is now more modern, and more efficient - thanks to a lot of hard work and continued support of the Windows App Community.
Unfortunately, I am unable to upload packages on GitHub Releases as for now it is being packaged manually and uploading the artifacts for every single package is far too much work.

Enjoy!
