mandos-monitor: Use Python's standard loggging module

* mandos-monitor: Use Python's standard loggging module, also for
                  warnings.  Suppress BytesWarning from urwid when
                  exiting.
  (log): New global logger object.  This replaces UserInterface
        log_message().
  (MandosClientWidget.__init__): Remove "logger" argument.
  (MandosClientWidget.using_timer): Wrap self.update_timer using new
                                    glib_safely() function.
  (glib_safely): New function to log any exceptions instead of letting
                 exceptions propagate up to GLib.
  (UserInterface.__init__): Remove "log_level" argument.  Set new
                            "loghandler" attribute, instance of new
                            "UILogHandler".
  (UserInterface.log_message): Removed.
  (UserInterface.log_message_raw): Renamed to "add_log_line"; all
                                   callers changed.  Also fix
                                   off-by-one error in max_log_length
                                   logic.
  (UserInterface.run): Add self.loghandler to logger "log". Wrap
                       self.process_input using new glib_safely()
                       function.
  (UserInterface.stop): Remove self.loghandler from logger "log".
  (UserInterface.process_input): Make verbosity toggle affect log
                                 level of logger "log".
  (UILogHandler): New.
