Process sandbox (Windows) stripping quotes passed as arguments

As described in museumsvictoria/nodel-recipes#77 (comment), the process sandbox strips quotes which are passed along from the App Launcher (and other nodes).

So "C:\content\hello world.mp4" would be treated as two seperate arguments, C:\content\hello and world.mp4

As suggested in that linked PR; making use of Environment.CommandLine instead of the class static void Main method, should resolve this issue.
