* mandos: Bug fix: Don't print output from checkers when running in foreground. Bug fix: Do not fail when client is removed from clients.conf but saved settings remain. (Client.server_settings): New attribute. (Client.__init__): Take new "server_settings" keyword argument. All callers changed. (Client.start_checker): Redirect stdout and stderr for checkers when running in foreground. (main): New "wnull" global variable for a writable /dev/null file. Do not restore settings for clients no longer in config file. (main/cleanup): Close wnull file object. Do not save client attribute "server_settings" * mandos-monitor: Update to work in Urwid 1.0.1. Adapt to work in both Python 3 and Python 2.
