Adding make_local for vfont/gpencil/group/freestyle linestyle/mask/scene/sound/text. Note that there are still some lose ends here, since some type are not handled by id_copy (Scene, Sound and VFont), which means in case a datablock of that type is used both directly and indirectly, localization will fail. Scene copying might be doable though (maybe with a simple new 'full shalow' mode to existing BKE_scene_copy?), not sure about sounds and vfonts... Situations where this becomes an issue should be very rare corner cases anyway.
