Bundling Electron apps

electron-builder has native AppImage generation, and there is a electron-builder appimage target for electron-forge. For Electron Packager and please see https://github.com/electron-userland/electron-builder#pack-only-in-a-distributable-format.

Don't forget to set a window icon (which will also be used for the Dock) with

win = new BrowserWindow({
   ...
   icon: path.join(__dirname, '/icon/Icon-512x512.png')
})

We'd be happy to hear whether there are better solutions.
