"show logo" in slideshow settings doesn't do anything

This wants to load about.png which doesn't exist anymore.  "about.svg" does,
but is a rather abstract background image for the about dialog these days, so
use "flat_logo.svg" instead.

Which requires moving the svg loader out of cui into sfx2 for re-use.
