fix. Failed to skin looted creature

Changes Proposed:

Currently, when you kill a group of creatures, and proceed to loot, for some reason, the first to be looted fails the skinning, even if the player's skill is high or even 450 (the maximum).
Area loot is interrupted if what is being skinned is different from a creature. This is in order to prevent the script from being executed on the bodies, when they are close to an ore, or chest or other element. The script should only be used when what is being obtained is the item from the body of a creature or at least, initially that was the original idea.

Example looting high level creature. Applying skinning.

This is the result, with low level creatures. But stripping and skinning the first of them.

Finally, we have the same as above. But skinning someone other than the first to loot.
