Detailed Description

QFileDialog plus generic extension support.

This is a simple hack on top of QFileDialog that allows a custom extension widget to be added to the bottom of the dialog. A button is provided for toggling display of this widget on/off.

For the placement of button and extension widget, it is assumed that QFileDialog uses a QGridLayout as its top-level layout. Other layouts will probably lead to a strange outlook, although the functionality should stay intact.
