App won't load if wowProduct no longer valid

[WainPetopia]

I just noticed for the first time that if the wowProduct in config.json is no longer valid then the app bugs out and won't load. It's probably not a big deal, but if there's an easy way to get a list of valid WoW products then could it choose one of those instead?

(My default product was still set to the Beta, and I noticed WDT stopped working when the Beta became invalid)
