Marco Bonardo 643d69f402 Bug 766799 - Notify hidden visits to history observers. 
Redirect sources and framed visits are considered hidden and thus not shown in
common UI history queries.  So far were not even notified, but the right thing
to do is to let the observer handle them based on its needs.
