Subject: tools: display screenshot in example gallery

Adding the option to display a screenshot on the
example gallery.

First, the script will look for an image with the same name
as the example, otherwise it will just get the first
in alphabetical order.

Pick-to: 6.0
Fixes: PYSIDE-1490
Change-Id: Ia0328c84206a3d66854197abe5ecad8d1d28abc5
