This commit adds Danger via GitHub Actions. Dangerfiles are ruby files
that have a DSL for interacting with GitHub. They can do arbitrary
things. See: https://danger.systems/reference.html
The point of this commit is to automate the process of asking people to
update the changelog. This is a really really annoying thing that we
have to do too often. Editing a pull request will automatically re-run
the check.
Truly trivial commits can be marked as trivial easily by using the
hashtag trivial in the PR body. This is really just useful for actually
trivial things. Most commits actually do need to have associated
changelog entries.
This changeset fixes several problems with the github actions build. It
removes the dependency on a repo script to install msbuild + VS. It
switches the shell back to cmd.exe, so that the scripts in build.yml
continue to run. It installs nuget via chocolatey, since that's not on
the path by default. Finally, it also uses built in MSBUILD to satisfy
the first statement.
