1/ The code used to manage the cluster configuration has been rewritten. SSID's
   problem (linux version) should be fixed with that. I hope new bugs won't
   follow ! :-)

2/ New symbols %D, %d, %H for respectivly Date (DD-MMM-YYYY), Date (DD-MMM) and
   time (HH:MM).

3/ Database updating is allowed. See the doc file.

4/ SHow/MEMleft gives more information (DOS version only).

5/ Checking the validity of protocols wasn't work properly. Fixed. Tks LA6CU and
   LA3WAA.

6/ A cluster link using the pavillon software protocol is now disconnected if a
   non protocol frame is coming in. This can happends if the link uses some
   NETROM type nodes (in case of disconnection).

7/ I finished to write the code for the PING command. Please try it and give me
   your comments if any.
