Improve launcher and game launch logic

* Don't hide the window/show deck prompt until ffxiv actually starts launching
  This saves several seconds of launcher disappearing and nothing happening
* Don't show the deck prompt in XLM mode (no manual swap is needed)
* Improve steam initialization: use SteamAppId, which is provided by whatever entry you use XLM on
  This allows for use on non-ffxiv entries for Steam regions without FFXIV
