Session now runs only the room this screen is in. It plays ahead of the server
with its own controls, guesses everyone else's, confirms ticks against the
server's frames and rewinds on a wrong guess. It keeps its lead by playing a
little faster or slower as the server says how early its controls arrive,
resends an edit the server dropped, and checks the server's checksums.
Gone with the peer-to-peer design: the host's decisions, the second arena game,
the view swapping and spectating (to come back through the server).
SAB_NET_STATS logs how it's keeping up.

Profile, member join/leave and building a fresh game move into the sim library,
and the packet reader and writer into protocol.h, so the server can run lobbies
exactly as clients do.
