Feature req: Specify arguments for restart with AutoUpdater

For me, this is more of a would-be-nice than a need, but I noticed that using the AutomaticUpdater control to restart the application does not restart it with the same command line arguments. In my case, we specify what hardware to interface with, so it might be `myApp.exe --hardware-model-1`. Then on a restart after an update, it would be started as simply `myApp.exe`, and we'd see a warning/error message about no hardware model being specified.

Granted that most people don't use command line arguments for UI applications anyway, but like I said, it's a would-be-nice feature for me; it might be a must-have for other situations.
