In working on my own repo [hop](https://github.com/Nickersoft/hop), which uses nativefier under-the-hood, I found it very troublesome to suppress log output when using the programmatic API. This PR just adds a quick "quiet" option which will set the log level to "silent" and suppress all electron and nativefier output (except for errors, of course).

It contains a weird mix of stuff and hides valuable files from view at the root of the repo. Better to have:
- Docs at the root
- Rest of the github/release-related hodgepodge (screenshots, scripts) in hidden folder .github
