    Gtk: Fix ownership of some GLists
    
    * gtk/src/icontheme.ccg: list_icons(): Glib::OWNERSHIP_SHALLOW -> DEEP
    * gtk/src/iconview.hg: get_selected_icons(): SHALLOW -> DEEP. Remove the
    TreePathTraits struct in iconview.hg. Use the one in treepath.hg.
    * gtk/src/recentmanager.hg: get_items(): SHALLOW -> DEEP
