Botania Dimension Blacklist/Whitelist

This mod is mainly intended for modpack makers that want to gate Botania behind a certain dimension, or simply prevent it from generating in certain dimensions without having to use something like COFH World.

You can add as many dimensions to the blacklist as you want, and no Botania flowers, tall flowers, or mushrooms will generate in those specified dimensions. 
You can also make it a whitelist, that is, a list of dimensions where the world gen is enabled and where any dimension that's not in the whitelist won't have Botania's world gen. To make it a whitelist, simply make the first entry in the blacklist an asterisk (*) instead of a number.
