Rebased onto current master and fixed the privacy module build: - privacy_item.hpp no longer includes privacy.hpp (it does not use the Privacy class); this broke the circular include that left PrivacyItem undeclared when privacy.hpp was reached first from privacy_item.cpp. - privacy_item.cpp now includes gtkmm/label.h explicitly, since Gtk::Label was previously only pulled in transitively via privacy.hpp.
