At the moment, breeding chiseled sheep yields wool lambs.

I'm opening this issue up for discussion about different things we could do with breeding sheep.

I think allowing modpack creators define in the configs which combinations of blocks breed to create what blocks would be awesome; I think the chisel groups idea is a good one too.

Forge have accepted my pull request for the baby entity spawned event. This opens up a lot of possibilities in this space.

Maybe they'll work like chickens in sf3?
