was not persisting across sessions. I added a new attribute to outliner "statedatasource"
that you can set to use for state, otherwise, if you are "trusted" it will use the localstore.
if not trusted, it will use an in memory datasource, which will not persist across sessions.
r/sr=bienvenu for the mailnews part, r/sr=waterson for the content part.
