This will ensure KiCad will be easily installable from the app stores such
as GNOME Software.
The screenshots probably need a better home. Not that it would matter
too much -- the Linux distributions do cache them with their feeds, so
the app store applications don't access them from this source directly.
Screenshots from the web [1] can't be used since they are too large for
use in the app store application. :(
