done:
* module api changed, vis_set is not close to vis_get, vis_supported
was added.
* exported these properties in emotion_object.
* gstreamer plugin now starts with no visualization.
todo:
* add xine support.
* make gstreamer able to dynamically change visualization.
PS: gstreamer module really needs a cleanup, losts of functions need
"static" or add proper prefix, including "gst" to avoid it clash with
other symbols.
