Some cleanup in widgets module. Deletion of GraphicsObjectContainer.

This commit deletes the uneeded classes/declarations since we have now
an inline support for QGraphicsObject based classes. QGraphicsLayout
bindings works the same way because the layout property has been added
to QGraphicsWidget. The only feature that is missing for now (because
of the deletion of GraphicsObjectContainer) is the anchoring support.
We will probably take a look on how to support this feature properly
with no wrapper.

-    \qmlclass GraphicsObjectContainer QDeclarativeGraphicsObjectContainer
-    \since 4.7
-    \brief The GraphicsObjectContainer element allows you to add QGraphicsObjects into Fluid UI elements.
-
-    While any QObject based class can be exposed to QML, QDeclarativeItem
-    provides a lot of important functionality, including anchors and proper
-    management of child items. GraphicsObjectContainer helps provide these
-    functions to other QGraphicsObjects, so that they can be used unaltered in
-    a QML scene. QGraphicsObjects, which are not QDeclarativeItems, and which are
-    placed in a QML scene outside of a GraphicsObjectContainer, will not appear
-    on screen at all.
-
-    A GraphicsObjectContainer can have one element inside it, and it must be a
-    QGraphicsObject or subclass which has been exposed to the QML engine.
-    The graphics object inside the GraphicsObjectContainer can then be used
-    like any other item in QML with the exception of not being reparentable
-    and not having the standard properties of QML items (such as anchors).
-
-    As the contained object is positioned relative to the container, anchors
-    affecting the container item will affect the onscreen position of the
-    contained item. If synchronizedResizing is set to true, then anchors
-    affecting the container item's size will also affect the contained item's
-    size.
-
-    Example:
-    \code
-    import Qt 4.7
-    import MyApp 2.1 as Widgets
-    Rectangle{
-        id: rect
-        property alias widgetPropertyThree: widget.myThirdProperty;
-        GraphicsObjectContainer{
-            synchronizedResizing: true
-            anchors.margins: 10
-            anchors.fill: parent
-            Widgets.MyWidget{
-                myProperty: "A Value"
-                myOtherProperty: rect.color
-            }
-        }
-    }
-    \endcode
