Updated for 1.4, made individual caps apply to the breeding event.

This should probably be separated into 2 pull requests but neither is very substantial.  This adds support for the new breeding items in 1.4 (seeds & carrots) and improves the support for individual animal caps in the breeding event.  I actually wrote this quite a while ago and I forget what exactly the last commit was meant to address :)
