Allow logging to a file on Windows

[nornagon]

With Chrome, --enable-logging --log-file=log.txt on Windows results in logs being written to log.txt. Electron, however, ignores the --log-file and always writes to the system debug log with OutputDebugString: https://github.com/electron/electron/blob/master/atom/app/atom_main_delegate.cc#L139

It's useful for telemetry to be able to redirect logs to a file, and there's presently no reliable way to do that on Windows.

Until there is better built-in support, I recommend electron-log. We created a Windows app and use that package, and it has some nice features.

It doesn't log Chromium's logs to that file though, which is important :)

This would be very useful, especially given that piping electron output to a file does not work. When I try to do that, a new console window is opened for every process, and nothing ends up in the file.
