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
