* mandos-monitor (MandosClientPropertyCache): Remove conversion of
D-Bus types to native
Python types.
(MandosClientPropertyCache.type_map): Removed attribute.
(MandosClientPropertyCache.conversion): Removed method.
(ConstrainedListBox): New; a ListBox which will keep the focus.
(UserInterface.__init__): Take new argument "max_log_length".
(UserInterface.divider, UserInterface.log,
UserInterface.max_log_length, UserInterface.logbox,
UserInterface.log_visible, UserInterface.log_wrap): New attributes.
(UserInterface.rebuild, UserInterface.log_message,
UserInterface.toggle_log_display, UserInterface.change_log_display):
New methods.
(UserInterface.remove_client): Bug fix: Eliminate double client
listing when an empty list gets a
ClientAdded signal.
(UserInterface.process_input): Add more key translations.
