Remove crossworld connections from dungeonsfull (#97)
* Stop inverted dungeonsfull from generating crossworld dungeon connections. * Inverted dungeonsfull fix - Force reusing an existing cave if there are not enough entrances to use a new one. * Enhance mandatory exit logic to ensure they do not block themselves, and also handle boundary conditions that often occur in inverted dungeonsfull * Split invalid connections into normal and inverted
