property_list.cxx: in verbose mode (toggle with Ctrl-'.'-entry) also

show "secret" values, that is: values of nodes with children. These
  can be used like all normal (leaf) properties, but their values were
  until now only shown in writeProperties() dumps. Also show the
  number of attached listeners. Example:    foo = 'bar' (string, AU, L3).

dialog.cxx: add warning message for broken <format>s; cosmetics
