* Re-worked the login-char-map packet spam mechanism

- mapserver no longer sends entire user list to charserver every 10 seconds; similar change done to the char-login connection
- user count updates are only sent when the value actually changes instead of servers polling each other every few seconds
- the servers now prevent interserver connection timeout explicitly by sending ping/ack packet pairs instead of relying on the usercount polling to do so; keepalive is sent every 'stall_time'-2 seconds
- removed the @refreshonline command as refresh happens automatically every 5 seconds
