Chemistry/Cooking pack. Attempt 2.

1. Fixed elf-a mutagen name. (Actually I'm unsure if "elf-a" or "elfa" is correct.)
2. Dried tainted meat + recipe.
3. Dried tainted veggy + recipe.
4. Simple recipes with human flesh are now learned automatically.
5. Tainted meat recipe.
6. Added canned clams as a component in cephalopod mutagen.
7. Added possibility to use serums in mutagen recipes when there is more than one dose needed.
8. Blob glob from tainted meat recipe.
9. Soap recipe.
Ideally I'd keep it non-hyphenated but we've already had the flamewar over elves in DDA.  I'll take this part as you currently have it.
