Able to add "Deep Warm Ocean" biome which doesn't exist

[Dannypan]

Via global ops one can add a "deep warm ocean" when this biome doesn't exist.

I had applied it thinking it real and when I tried to select it an error came up saying biome 47 can't be found. Did a little research and "deep warm ocean" is an unused biome.

It can be removed from the global ops list of biomes.
