Entity Y Spawning Limitation and Custom Entity Spawning compatible with Biome Dictionary

- A limit (range) in the y-axis of a spawning custom enity (ex: cave mobs that only spawn underground or creatures which spawn only above ground

- Instead of listing the biomes where an entity can spawn, having different biome catagories like the biome creator where for example a certain mob can only spawn in forests which would be compatible with other mods that add biomes that are classified as a forest in biome dictionary, thus allowing the mob to for example spawn in a Biomes O Plenty biome.
