Pickelhelm

Urchin v1.4 "Pickelhelm" adds compatibility for a new build file, "BASh/nc" which sets up a netcat listener on a UNIX device and outputs it into a BASh shell.
*Note: this is a blind shell, meaning that a connector to the remote shell will not be able to see the output of any commands. Also, this listener is in a while loop, so if the connector closes it, they should be able to connect unless the host closes the listener.
