Mostly a straight copy & paste of the files. The only significant change was to move the localizable strings from Properties/Resources (RESX) to Res/Strings.xaml (Resource Dictionary). I expect a number of strings will no longer be needed, since WPF lets you put more of the UI/UX logic into the design side. I also renamed the namespace to SourceGenWPF, and put the app icon into the Res directory so it can be a resource rather than a loose file. I'm merging the "Setup" directory contents into the main app since there wasn't a whole lot going on there. The WPF Color class lacks conversions to/from a 32-bit integer, so I added those. None of the stuff is wired up yet.
