by using the graphicsobject directly, make it
possible to pass a full geometry at the applet creation by script
adapt the config dump in javascript to use it
the api containment.name was incorrect and broken,
(using it it actually breaks the whole layout since
breaks the containment->activity association)
in order to make it coherent with the other activity
related api, add global functions activityName
and setActivityName
it's not very object oriented but is coherent with
the other api already in place
(as there isn't an "Activity" class binding)
