WM: added area-listener, which can be used to tag refreshes for either the drawing call, or use the new ED_area_tag_refresh() function which will automatically call, after all notifiers were handled, an the spacetype->refresh() you provided. Added for Joshua, after reviewing Action/Dopesheet requirements. Joshua: I've made two dummy functions in space_action.c: - action_listener() - action_refresh() Wich now does a printf on activating a new object.
