Almost all of the events have been eradicated, which significantly improves both generation speed and playthrough calculation.
Previously, checking for access to a location involved checking for access to each panel in the location, as well as recursively checking for access to any panels required by those panels. This potentially performed the same check multiple times. The access requirements for locations are now calculated and flattened in generate_early, so that the access function can directly check for the required rooms, doors, and colors.
These flattened access requirements are also used for Entrance checking, and register_indirect_condition is used to make sure that can_reach(Region) is safe to use.
The Mastery and Level 2 rules now just run a bunch of access rules and count the number of them that succeed, instead of relying on event items.
Finally: the Level 2 panel hunt is now enabled even when Level 2 is not the victory condition, as I feel that generation is fast enough now for that to be acceptable.
