Make this a whole lot more useful

This is a placeholder for the "proper" patch system, so there's a place for some notes/discussion. At the moment I've got a patch file in Bocfel's (as-yet-unreleased) syntax, both for "Robot Finds Kitten" and "Transporter".

A few notes:

• This probably should be a JSON file or similar, with scripts to convert to an appropriate syntax for whatever interpreter needs it.
• There will need to be some mechanism for specifying the conditions under which various patches will be applied:
  • My Bureaucracy patch, for example, only works with timed input, so shouldn't run in situations where it doesn't exist.
  • My Trinity & Beyond Zork patches for handling CARRIAGE-RETURNS are meant for Glk, and will look odd in interpreters that behave like Infocom's.
• There probably needs to be some system for at least differentiating Infocom from "other" patches, which may be as simple (but inflexible) as a boolean, or more general like a tag system; this is because I don't anticipate removing Infocom patches from Bocfel so the generator will need to be able to exclude them. I suppose the generator itself could use Zarf's obsessively complete catalogue info to exclude Infocom games, though.

PR #2 implements the JSON-as-canonical and a program to convert.
