Fully implement connections from public networks (Internet)

[GoogleCodeExporter]

ORP v1.1 moved closer to fully emulating the protocol.  Specifically, the
player now sends SRCH UDP packets and if no replies are received, it does
not try to open a TCP connection.  The UDP portion of the protocol is
required for game/application launching.

Study the PSP traffic in detail as it pertains to public (internet) network
connections and properly implement the protocol so it works from the
internet with the correct TCP/UDP forwarding.
