This mod has been mostly obsoleted by 0.4.13's mushrooms

so simplify and revise it to act as a "3d-ify" mod for them.

Unidenfied spores aliased to the regular default equivalents
poison and essence aliased back to their originating mushrooms
identifier aliased to mese crystal (most expensive component of it)
everything else aliased to their default counterparts

spores are not dropped from digging dirt with grass anymore
