Adds Archipelago support for Zork Grand Inquisitor, the 1997 point-and-click PC adventure game.
The client (based on `CommonClient`), on top of its regular Archipelago duties, fully handles the randomization of the game and the monitoring / modification of the game state. No game modding needed at all; the player is ready to play an Archipelago seed if they can play the vanilla game through ScummVM.
The "reverse engineering" (there's likely a better term for this...) of the game is my own original work and I included an MIT license at the root of my world directory.
A PopTracker pack was also created to help people learn the game: https://github.com/SerpentAI/ZorkGrandInquisitorAPTracker
