Ling sting usability improvement

Tested - it works
Replaces the different sleep() calls from the slime reactions for spawn() calls. Now you can't inject the same reagent into different cores generating runtimes.
Standarized some of the code of slime reactions, hopefully they won't be creating issues.
Removed the plasma bluespace slime reaction. It was so bad. SO BAD.
Nerfed EMP's against augmented limbs

Because there's not much benefit to only having a few limbs augmented,
and 120/60 damage just silly.  For comparison, cyborgs take 20 damage
total from an EMP and 5-10 stun, and humans take 60 brute damage for
being just outside the gibbing range of a bomb.

This PR brings the average damage from a strong EMP to an aug down to
48, and from a weak EMP down to 30.  The stun against a full aug is
still very likely to be around 10 or 5, respectively.  This is on top of
having weapons drained, headsets disabled, etc.
Gives fuel tanks a fire_act()
Fixes an oversight in my slab code

Initial code now works as intended, did not realize the recursive mob
check was looking for clients, now it looks for any mobs.
