Style QFileDialog

All file dialogs are picking up the material design style but it isn't a good fit. I think it would be best for this dialog to just use the system style of each user.

I've tried adding the following to the end of style.qss in the hope that it would clear up the style for all its descendants, but that didn't seem to do the trick, so this will need some deeper investigating.

QFileDialog *
{
}

I think the static function of QFileDialog may use the native system style but we also had problems with it in gazebo where some users were getting blank dialogs.
