worked on get_peers some more

get_peers now returns an array of dht_nodes or peers bundled in a class,
ill need to add functionality to these classes to get proper console
formatting done.

Also this means that now i can work on recursing over these returned
nodes to get find/get more peers from the dht.

Changed the function XJIOP back to a hard coded info_hash just
temporarily.

Also found bug where last item in returned array was empty will have to
fix that.
