Subject: Clean up docs for graphicsview.

* doc/snippets/graphicsview.cpp is moved from the qtdoc repo
* doc/images/graphicsview-parentchild.png is taken from 4.8

There are still some problems with references to examples, but
Casper meant that Jerome was working on that, so I'll leave
those fixes out.
