- SYS command crashed DxNet. Fixed.

- axutils invalid symbol fixed (linux). Special thanks to F6FBB who gave me
a hand fixing that. Tks also to the linux beta testers.

- Connection Filter : CTEXT is not sent to an undeclared user. Fixed.

- Update field is wrong after 2h24m of run ... just a math problem which is
fixed. Thanks EA3BKZ.

- A message will appair when a message (MSG1, MSG2, ..., in the language
files) is required by DxNet but does not exist.

- The linux version was not managing correctly the paclen values set in
axports. Fixed. Thank SM5HUA.

- Remote database implemented (PC44, PC45, PC46). Up to 40 remote databases
  may be defined.

  The remote database are defined in SYSTEM\REMOTE.DAT like following :

  --- system\remote.dat file ---
  database_name		cluster		#Optional title

  IMPORTANT : The field database "database_name" must match exactly the one
  used by the adjacent cluster.

  For exemple, assume you want to allow you DxNet to search the remote
  database BUCK on F6BEE. Your REMOTE.DAT file will include the following
  row (the keywords are not case sensitive) :

  --- system\remote.dat file ---
  buck	f6bee	#Buckmaster's callbook database

  NOTE for linux users : if you are running the buckmaster interface for
  linux, you must modify your configuration if you want to allow
  remote access to the buckmaster database. Please read the /doc/README.buck
  file supplied with the buck_interface-990322 package.

- 3 new utility prgrams created : PURGDX, PURGWWV, PURGANN. Copy this files
  in the extcmd directory. This 3 programs use the same optionnal
  arguments :

   PURGE?? [p=BinPath] [d=#n_days] [v]

   where : - [p=BinPath] specifies the directory in where the binary file
	     is located.
	     The default directory is ..\SYSTEM\BIN.

	   - [d=#n_days] sets the number of day (#n_days) after which a
	     data will be deleted from the binary file.
	     By default, this value is set to 30.

	   - [v] prints the version number.

   Example : PURGDX p=C:\DXNET\SYSTEM\BIN d=7
	     PURGWWV d=15
	     PURGANN p=/usr/local/dxnet/system/bin d=30

- Small bug fixed in PURGMAIL utility.
