Enable custom biome check in spawning. This allows mods to overide the check in singlenode and other mapgens that do not support biome API. (#4217)

Browse source 
Some older mapgens do not support the MT biome API. Singlenode and I think v6 also. This allows mods to overide the biomecheck in mob spawning to return valid biomenames and customise this.
