Prepare Build for macOS

[komanton]

1. Take the distribution build of electron for macOS
2. App files from src to the build for macOS
3. Rebuild robot package, see distribution instruction in readme
4. Test app
5. Zip all files, like for windows.
6. Publish it into releases

Another word, we need the same, like here https://github.com/komanton/dicty#distribution but for macOS
