* [vcpkg] Add initial JSON support This adds a JSON parser, as well as the amount of unicode support required for JSON parsing to work according to the specification. In the future, I hope to rewrite our existing XML files into JSON. Additionally, as a drive-by, we've added the following: * add /wd4800 to pragmas.h -- this is a "performance warning", for when you implicitly convert pointers or integers to bool, and shouldn't be an issue for us. * Switched Parse::ParserBase to read unicode (as utf-8), as opposed to ASCII * Building again under VCPKG_DEVELOPMENT_WARNINGS, yay!
