PiBox

Right now you have to specify which interface you want to listen on. This can be easily fixed to listen on all ports if -H is not specified by making the socket ids for IPv4 and IPv6 arrays instead of a static entry. Since the list will always be short (we can limit it to the first X interfaces discovered) this likely won't have adverse affects on performance.

I need this so I don't have to specify which interface to listen on when launching hawkeye, which would require changes to piboxd that I don't really want to make (for parsing %h fields in commands).
