Rewrote mob spawning

- EntityWizzrobe no longer tied to MagicType, but WizzrobeType
- Added localizations for MagicType names

determining factor in which mob subtype will be spawned
- Standardized config loading of biomes to all occur in postInit phase,
moving BossType's config into the class
- Standardized entity names
