[MWR] Mutagenic serum!

Because the only thing better than a lizard/beast/drug-fiend/ubermensch/fish-person/dinosaur potion is a lizard/beast/drug-fiend/ubermensch/fish-person/dinosaur INJECTION.

In general, these cost two of the oral doses for an injectable dose which can accomplish 1-3 mutations, at a minor Pain hit.  Some have more exotic effects.  Recipes are learned through a book that spawns in chemlabs and lab dorms; the top-flight stuff (Medical & tier-10) has both recipes included in their own item.

Hearing no commentary, I'll go ahead and move this to merge-when-ready.  If you would, please?
