Subject: - Added variable other_mapserver_count to chrif.c which holds total
 count of connected map-servers. By using this we prevent sending unnecessary
 packets to the char-server when there's no more map-servers connected. -
 Affected packets are whispers, announces, party messages, guild messages.
