Force non-delta snapshot on map_restart during playback

Browse source 
snapFlagServerBit toggle alone doesn't clear client entity
interpolation state. Also reset deltaMessage=-1 for all active
clients, forcing the next snapshot to be full (non-delta). The
client receives deltaNum<=0, clears old entity state, and
renders all entities at their new positions without interpolation.
