Comments noting TransientActionFactory.
Allow configuration changes to be saved for TopLevelItem’s which are not AbstractProject’s or Folder’s.
Only a partial fix since the action factory does not yet allow the config history details to be displayed,
but at least we are displaying the operation/date/user and storing the XML diffs,
so a future version of the plugin could display historical details.
OK, testIsSaveable is actually checking for a non-TopLevelItem AbstractProject. Consider these saveable.
