when the plugin is loaded, the reulsting object should be a subclass of the 
new Applet, which would be either a QML item or a QGraphicsItem.

for a QGraphicsView based shell, it shouldn't really care, as i understand it. 
both can be popped onto the scene.

for a QML-only shell, it will just need to discard any QGraphicsItem entries. 
it can also filter on the X-Plasma-API entry.

i suppose the Big Question then becomes: will we support QML applets written 
in C++ (which then export their QML root time via some API)? if so then we'll 
probably end up needing to add X-Plasma-API= entries to even the C++ widgets 
that are implemented in QML, and a special api name for it, e.g. 
C++Declarative that Applet can treat as "regular C++". then the C++ QML Applet 
subclass would need a virtual method by which to return the root item, which 
seems a bit messy. thoughts?
