A Z device core for playing text-based interactive fiction.

This program currently supports most of the Version 3 Z-Machine. This is enough to play the vast majority of Infocom's catalog. Later Infocom games used version 4, 5, and 6 of the Z-Machine, and those will currently not run here. Most modern Interactive Fiction is built with a tool called Inform and usually targets version 5 at the lowest; these games currently don't work with this project. Maybe later.
