66 million rows in QTreeView

Inspired by the recent work with gtktreeview I decided to see how far I could push the item view framework. Modifing the interview demo from 1000 rows by 100 columns I was able to get around sixty million rows by twenty million columns. Once I would go past that (somewhere around ~75 rows and ~25 columns) I started hitting some int overflows, but even with showing that model in the tree view, list view and table view took about 1 second (including showing the icon, text etc) for the application to run. Not bad I must say.
