Network synchronization needs to remove characteristics

now in China almost can't use zeronet. gfwl can detect the network message and block it.
Network synchronization of zeronet needs to be removed characteristics. just like shadowsocks. or let it just like the https message.

The issue names no file, test, or entry point; begin by locating ZeroNet's network synchronization implementation and its message-handling path. Compare the current traffic characteristics with the referenced Shadowsocks and HTTPS behavior, then define measurable tests for whether synchronization traffic is less identifiable without breaking peer communication.
