Vampire fixes.

Fixes: Full-power xray now works.
Enthrall reduced to 150 bloods.
Vampires fry! in starlight.  You'll be dead in seconds.
Bats buffed.  They're pretty strong now.  No longer eat each other since
you only get one bat.  May be nerfed in the future.  Not sure.
Some blood fixes.  You don't lose blood if an ability fails now.  So if
you don't move to cancel it after trying to hypnotize yourself, that's
totally your fault.
Added a color to clonetox.  Made cyanide's metabolism rate less stupid
high so it's actually useful maybe, or could be if it were ever used.
Telesci fix.

Angle offset got added back in, which makes telesci unuseable except for
what I usually use it for.  Which is z-level hopping.
Actual telesci fix.

Woops.  Nixed the wrong variable.  Successfully negates elevation
offset.
Mostly guns changes.

Stun revolver now fires electrode/high, like all other tasers.
Temperature gun revamped.  Utility weapon.  Gives people major slowdown
and some burns.  Dangerous against civilians, but honestly less than
someone with a laser.  Great utility.  Intended for xenobio.
Energy crossbow changed to stun in two instead of stun in three.  Pretty
powerful now.
Decloner buildable.  Does 40 cloneloss, 40 radiation.
Chemsprayer- cranked up research levels required bigtime.  Now needs
plasmas to build.
Mech teleporter enabled because why not.
Diamond pickaxe r&d design commented out.
Sprite added for battery-less baton.  Adding code is trickier and I'm
too lazy right now, so just the sprite is in.
Vamp weaknesses

Vampire weaknesses added.  Null rod and holy water.
Shadowstep fix

I moved the blood drain to the lighting check by accident so whenever
you use it, it drains all your blood because it checks the lighting a
million times.  This has been corrected.
