Downstream update
Added new black surgical scrubs

Potentially for new mortician job.  Sprited by Pancake.
Runes sprite change

by Pancake.  correct rune combinations now glow correctly when written
too.  runes are larger than previously, taking up most of the tile,
where as before they took up about 2/3rds of the tile.  I personally
like it.
Wubbledaddy's Pennywise costume fix
Cult communication talisman fix
Cult talismen from paper fix

Talismen made from starting cultist stack now equip to backpack, pockets
or hands.  Will not use up a paper of the stack if the talisman cannot
be equipped.
Gravity mega stun fix
Possible cloned cultist view fix

Needs live testing, should fix the problem of the mask only being able
to track a cultist's first body, and not being able to follow them if
they've been cloned.
Fix for Ryetalin

Cures on a chance based on volume of ryetalin injected, on_mob_life.
TURNS OFF ALL MUTATIONS!!

// 1 volume = ~2% chance
// 10 volume = ~17% chance
// 30 volume = ~38% chance

Returns SE to mob creation values (now set in dna2.dm)
Fix for hardsuit modifications

When suits are turned to tajaran or unathi types, any helmets on the
suit are put on the floor.
