ars_Login(server, username, password, lang, authString, tcpport, rpcnumber)
      lang, authString, tcpport and rpcnumber
	are optional. 
"lang" is the language the user is using. If not specified, the default will be used.
 
	    "authString" has something to do with the Windows Domain. I
	    don't have any more information about this parameter. Pass
	    undef to be safe.
 
	
	If you want to use a private server, specify tcpport and
	rpcnumber. 
	If you pass an empty string as the "server" parameter,
	ars_Login will attempt to identify one.
      
undef for invalid number of arguments.
      Example:
      $c = ars_Login("","jmurphy","blah")
      
      
      $c = ars_Login("yourserver.example.com", "jmurphy", "blah", undef, undef, 9000, 390680)
