Iuse-in-progress

Lest people think I'm slacking.

This still needs testing and support files, but feel free to look at
Chimera and the others, let me know what you think.
Tweaks & Purifier

OK OK I'll make an injectable Purifier too.  ;-P
Morale support

If find-in-files is right, these and the iuse are all the code I need to
make the morale effects.  Seems too easy?
The serums themselves

I kinda liked magenta mutagen better than light_green.  So I let some of
these vary their colors.

Check the health, nutrition, etc effects: mutating should take a lot out
of you.  Erred on the side of playability at this point.
Fixes & factory

OK, got all the syntax worked out.

Problem is, morale is marking the morale-effects as "moodswing" when it
should be "took X mutagen".  I'll try moving it to the consumables.
I knew it!

Morale effects are named in player.cpp in the precise order they're
listed in morale.h.  TMYK.  <rainbow!>
Recipes & stat tweak

This should be everything you need to take these into the game.

Makes Alpha a little easier to find, too.  I decided one point in one
item group was a bit rare.
