Partial Safari Game implementation

This adds some infrastructure for the Safari Game, specifically;
- The guards who let you in; the ticket is given and Safari Balls are provided; you also get the leaving early and so on. Bit janky at times.
- Infrastructure for the step system, albeit unfinished; the steps aren't initially counted and there's no kicking out process yet.

All in all, it's now playable, but the loss conditions are not yet finished. I shall now lay down in a dark room.
