Fulcrum/Logger.cpp
Calin Culianu 2547dc35cb Added SysLogger for -S option which actually uses unix syslog()
On Windows it still prints to console, however (without timestamps).

Note that syslog mode doesn't produce any debug output even if -d is
specified (at least on macOS) -- probably the sysadmin needs to
enable debug logging.
