Pass command line arguments to packaged program on Windows

[TheGreatCabbage]

Thanks for this excellent plugin. The only problem for me is that command line arguments are necessary to my program, and I need to be able to supply them at runtime. My pull request makes command line arguments usable on Windows only.

I noticed that any arguments passed to the .exe cause it to create an example config instead of running the packaged program. To allow arguments to be passed to the program, I modified Program.cs so that only a single argument, --example will trigger this behaviour.

To clarify the new behaviour, here are examples for a program packaged as TestProgram.exe:

.\TestProgram.exe runs packaged program with no args

.\TestProgram.exe --example creates example config

.\TestProgram.exe --example testarg1 runs packaged program with args --example and testarg1

.\TestProgram.exe testarg1 --example runs packaged program with args testarg1 and --example

.\TestProgram.exe testarg1 runs packaged program with args testarg1

.\TestProgram.exe testarg1 testarg2 runs packaged program with args testarg1 and testarg2
