Title: Prevent crash from division by 0 in growth rates

Simply put, setting any of the growth rates to 0 in your Spigot.yml crashes the server when any of the blocks are loaded. This will force the growth rates to default if detected.

Was planning to merge this into the growth rates patch, but it kept causing issues for me. If anyone can give me a way of doing so, I'll rebuild the patch.
