Added MSIX installer creation option

This is still in testing. I've done some testing with our internal systems, and I now want to open this up to the community for additional feedback. All comments, suggestions, and test suggestions or concerns are welcome :)

Note: The logos that look vaguely like Java's mascot (Duke) are just placeholders. I am hoping to include a mechanism with a default logo, and then an ability to specify your own when running the build script
