Last human plugin.

Last human plugin.

Well it's still not final, but some guys know code well so they can correct mine.
Notice it works well. (Tested only on zp 1.25b...) You can compile it and use, and ofc report bugs.

Q: What plugin do?
A: Announce in chat Who is last human and plays music you choose.

Q: How turn music on/off?
A: Type in console or in chat "lasthuman" without ""
