2.5

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.
