Github actions for build

[mr-islam]

Free for open source, and would make life simpler

There's a nice electron build github action package, but it might be better long term to handcraft the actions

Watched fireship's video on this, looks GH actions look much nicer than my experience with Travis a few years back!

This is high priority… really getting tired of making builds manually

The GitHub workflow works amazingly! The procedure to use it now and produce a new release:

1. Create a draft release and number it with a new version, that matches a bumped version from the package.json
2. Manually run the action and wait
3. Packages are built and artifacts are ready for testing
4. Write a changelog and publish the release
