FileTransferClient: password is output if LogWriter LogLevel is set to Verbose

I am using a LogWriter for the FileTransferClient class which descends from LogWriterBase.

If LogLevel is set to Info, the password is written out as **********. e.g.

Command: USER sparky
Response: 331 Password required for sparky
Command: PASS **********
Response: 230 Logged on

However, if the LogLevel is set to Verbose, the password is written to the log. e.g.

I can use a regular expression to replace this in the overridden Write method, but it should probably be changed to work the same way as LogLevel.Info?
