This is a cosmetic fix for the sidebar.
The highlight contrast is too high now that
the background is darker.

Since we use addAutoReleasedObject we would rather unclean call the
class destructor.

This makes the qemu run button appear/ disappear once we add a maemo
target to an existing project.

Don't use the dynamic property "HasFormEditorItem" any more when
checking whether childs have to be drawn directly by it's parent.

The problem was actually introduced with the new dynamic metatype
object (NodeInstanceMetaObject). At the time the dynamic property
"HasFormEditorItem" is set in
GraphicsObjectNodeInstance::createGraphicsObject(), the new metatype
object hasn't been created & attached to the object yet. The dynamic
property was effectively lost when the metatype object changed, leading
to multiple drawings of the child item.

This fix replaces the "HasFormEditorItem" property by directly asking
the NodeInstanceView whether an item draws itself or not.
