Feature Description:

• Currently, it seems only Biomes O' Plenty and Natura wood planks are supported.

• This feature would allow any ore dictionaried planks or wool to be able to be crafted into dog beds, allowing many more variants.

The OreDictionary has been replaced by tags in MinecraftForge/MinecraftForge@afead63.
I believe tags can change during the game, but all registry objects need to be registered at the start
