Alpha mutagen

Item, mutation categories, spawn locations, recipe item, mention in the
Lab Notes, actual recipe, iuse flag, and dreams.

I *think* that should be everything?
Lizard Differentiation

Lizard-y goodness: broke their eyes out into their own line and gave 'em
their own tail.  (Which is now the prereq for Club Tail, but I'm pretty
open to changing that.  Only critter to get that...will be the Chimera,
if that lands.  So far it doesn't actually have a category. )
Tail Support

This makes the tail actually confer the Dodge bonus and administer the
whapping.  It's strictly better than the Long Tail; I'm open to knocking
the bonus down to 1 if people like.
IR support

Here's where IR-vision mods go.  I think.
Extra close-paren

Fix'd.
Chimera mutagen

Same idea as Alpha, now with files individually committed so hopefully
it's easier to sort through.
Chimera recipe-item

Yeah, I'm trying to be Creepy here.  Lemme know if you'd rather I not
create lore for these things.
Chimera lab note

Special thanks to Cepheid on the IRC for volunteering to be the lead
researcher here.  It's surprisingly difficult to find people willing to
take credit for wildly dangerous and inhumane mutagens!
Chimera MutCat

Helps if there's an actual category.
Chimera dreams

Breaking up the syntax works a bit better, IMO.  Cf. the Schizophrenia
trait.
Chimera item-grouping

One thing I'd really like to do is get the item groups for Lab
chemistry-rooms and School chem-rooms split.  Or have another group for
Lab dorms.  Something.

Researchers absent-mindedly leaving these in the fridge is only so
funny, but I much prefer that to having classified, bleeding-edge-new
chemical formulae and protocols for their show up in a school building.
Chimera recipe

Takes longer and more power, but 4 components rather than 6.
Chimera iuse

And that should do it.
Lizards now Cold-Blooded

Done!
Simplify counters

Since the JSONs don't seem to support custom counters, went to generic
and am hoping for the best.
Semicolon fix

Thanks, Kevin.  I should have guessed.
Deadlier Venoms

Well, more so than they would have been.  Right now Lizard's crap but
all the others ought to have some redeeming features.
Bail out of add_rain_to_container() if we don't actually have rain to add. Fixes 4175.
KF Techniques

OK, that should be all of 'em.
Adds medical mutagen.

A mutagen specifically designed to augment medical treatments. Provides
some cool benefits, but comes with the risk of some very nasty side
effects.
