{{Quickfixn}} Masking passwords in logs

[Grant Birchmeier]

Password-masking in logs is something that I do want to implement soon
(issue #949 is open for it).

However, you are incorrect in saying that "this [legacy ILog
interface] implementation
is deleted."   *It's not deleted!*  Yes, we did add ILoggerFactory support
in the latest release, but we kept the legacy ILog support intact.

So for now I suggest you just keep using the same ILog implementation you
always used.  It should work!

(If it doesn't work, please let me know and I'll try to fix it!)
