[qemu-web PATCH v2 06/16] Rework display of screenshots to use a carousel slider

["Daniel P. Berrangé" <berrange@redhat.com>]

We have a number of screenshots to display, with three fitted across the
width of the screen. The screenshots dominate the usage of screen real
estate on the front page, with other relevant information off the bottom
of the page.

As a step towards increasing the information density of the home screen
replace the horizontally presented screenshots with a rotating carousel
of images.
