Title: Corrected segfault when registering new biomes.

Whenever addBiome discards a new biome (more than 255 biomes, or biome registering process already finished), it deletes it.

The code afterwards assumed the biome could not be deleted, and evoked it for a streaminfo print.
This fix corrects that.
