Add the template for the new LuminaThemes library class (not integrated into build yet).

This class will provide a consistant look for all Lumina utilities, while also allowing the user ways to easily modify the themes/appearance and have it take effect immediately. I also plan on extending this framework to save the completed stylesheet for *all* Qt-based system applications to use (providing an easy way to customize the feel of the system).
