Built out a configuration file for the main manager app so you can customize things like where it pulls its deck data from.  Wrote SkillCardDeck's XML reader.  While I was at it, I dumped the various skill decks to json files, that'll be easier to work with anyway.  Also gives us something cool to show off to the thread.  Oh, and added a few quality-of-life extensions that make messing with strings less of a pain, and allow us to store more information in enums if we want.
