* Merge from Debian unstable. Remaining changes: - debian/patches/07_bookmarks.patch: Add Ubuntu-specific default bookmarks, borrowed from Firefox - debian/patches/81_ubuntu_force_update_bookmarks_menu.patch: update the bookmarks menu every time the internal structure is changed (needed for the indicator application menu to work correctly). - debian/patches/ubuntu_titlebars.patch: Use traditional titlebars for non-GNOME sessions
