Implement a lookup to find out the mimetype for an icon and then supply
the needed icons with your app (or check wether the OS helps you with
the icons). Qt doesn't have any support that, the icons for directories
are most probably hardcoded and shipped by Qt.

Create a proxy model on top of the filesystem model that creates the
order as you want it.

The reason is most probably that the model simply supplies QIcon()'s
that are only 16x16. You'll have to change the filesystem model to
supply differently sized icons.
