Added a more effective way to make bolts, that includes feathers. Feathers now are given regardless of the size of the creature that is butchered.

Nervous Tissue can be turned into Sinew thread which can be used specifically to craft bolts. Happens automatically, as some creatures don't provide Nervous Tissue due to their size.

Next up, metal bolts, slings, and pellets.

I've also been experimenting with turning people into scrawns once they are bitten. However there are a few numbers which I am not aware of what they mean.

I'll do some science in my current game, hopefully I don't need to regen in order to see the effects.
