TPG.Net.SyncLimits

Broadcast both teams' current prop/weight/point usage and the max limits. Weight is sent in 500-unit steps (math.ceil(weight / 500)), not raw, to fit the 13-bit field; the client is expected to multiply back out. Points get 20 bits on the max-limits field specifically to cover up to 1,048,575, per the inline comment on that line.
