Ling buff per request and some coder fluff

Doubled default ling chem regen
Added poisonous sting that makes around 20 tox damage over time, also
makes target drunk and deals braindamage
Renamed proboscis into stinger because after reading wiki i dont like
proboscis anymore
Corrected a mistake.
Removed useless parameter
Woops
The icons and some inventory change

Since my personal icons were considered ok by some people i used them
Added new one for poison sting and tiny tiny bit changed the older ones,
also proboscis is still there just because
Also now put_in_?_hand will check for ABSTRACT flag, things with it will
be put in hand anyway
With this even while downed you can sting someone if you are quick
enough to do it before sting gets deleted from your hand(100% hack but
whatever)
Things like not dropping items from hands completely and other stuff
cheri suggested to make after we switch to v500
If you will find any bugs just tell and ill fix them
Thats probably it, ive done everything i wanted and implemented
everything i was asked for
Now will hope this PR will be merged, would be sad to do all this work
for nothing
Abstract things stay in hand while on the ground

This means 2 things
1 - you can sting while stunned/weakened and so on
2 - if you are not stunned/weakened but lying - you can grab things
All this ERP potential

Delta : Pinpointer now points toward the AI.

Pinpointer now points in the malf AI direction (so it won't track
innocent AIs), and follow it through shunting, or if it goes back to its
core after shunting.

Bloody hell was it a pain to just test that.
A lil' bit of commenting.

Who the hell reads those commit comments anyway?

Moved up Bump() in silicon.dm, and tested it.

According to my tests, unachored AI and Borgs behave as normal when
bumped by a mob.

A human can swap places with a borg if both have help intent on when
moving...
But a borg can't swap places with a human if both have help intent on,
if it's the borg that's moving. Apparently it's a normal behavior,
tested it on Sibyl.

AI don't have intents so they just get pushed.

pAIs aren't affected by bump, as they seem to act like as objects when
walked over or thrown.
Decoys seems to be some old MALF module that isn't in use anymore, so I
didn't touch it.
