- disable the autoupdater if running as mas (was not working anyway, just logging an error on every start)
- replace check via app.requestSingleInstanceLock() with LSMultipleInstancesProhibited in Info.plist
  due to https://github.com/electron/electron/issues/15958


- Quit the app also when all windows are closed to conform to macOS Human Interface Guidelines
  Comments from review:
  If the application is a single-window app, it might be appropriate to save data and quit the app when the main window is closed.
- "asarUnpack": "**/*.node" to also sign the native addons when packaging
- add the required mas-specific entitlements which include the app-sandbox key

Apple's documentation suggests that apps should be shipped as universal binaries
to simplify the process for the users. See eg. https://developer.apple.com/documentation/apple-silicon/porting-your-macos-apps-to-apple-silicon



Also update electron-updater to latest version (matching electron-builder version)
as part of this.

Just marking the remote control feature as disabled without explaining why
was not at all helpful to end users needing this feature.  So link to a couple
of pages to help them understand the reasoning.  It may even attract
developers to work on a fix.

Several fixes and patch-updated bundled Chromium.
For details see https://github.com/electron/electron/releases/tag/v12.0.1

In electron utils 2.0.15 we mark them as protected content, but on macOS
WebRTC uses a low level API which sidesteps that. An extra command line
argument is passed to fix that.
