Basically some items were not properly remove in the BSP which means
that if you delete one of items, the BSP tree may contain dangling pointers.
The problem was in removeItemHelper in QGraphicsScene were the child
were removed after reparenting to 0 the topmost parent. The
sceneBoundingRect for children was invalid which means that we were removing
them in the wrong position inside the BSP. Reparenting to 0 means that the
sceneBoundingRect will be the boundingRect but wasn't the case before
(for the topmost parent).

The problem was that we didn't regenerate the bsp when adding
items after calling QGraphicsScene::clear.

This revertes d39a62720ba67a0fa6e4e37519d22f14c7b7404e
(we had to do it with the old implementation, but the new one have
untransformable items included in the indexed list. The only difference
is that untransformable items are also in the untransformable list;
otherwise in the bsp tree).
Auto-test included.

The chip demo was unbelievable slow, so I investigated and found out
the bsp always returned almost all items in the tree (40 000 in this
particular case). It did so because the tree was initialized with
an empty sceneRect. The sceneRect was empty due to a lacking signal-slot
connection, resulting in QGraphicsSceneBspTreeIndex::updateSceneRect
never being invoked.
Auto-test included.

We basically add a new index that implement the old BSP logic but in a
separate class instead of living into the QGraphicsScene. It will be
much more easier to add a new index method or for people to use their
own
