revised icon loading on Windows and packaging again

* We don't need the PNG icons on Windows as the compiled-in ICO should suffice
* Ship the dependencies of the SVG pixbuf loader.
* The PNG pixbuf loader is still distributed, as we at least need it
  for loading the icon theme.
* Install a loaders.cache - without it, the pixbuf loaders won't be found.
  This file can be generated by gdk-pixbuf-query-loaders but apparently has
  to be modified by hand.
* Regenerate the icon cache using gtk-update-icon-cache.
* Icon themes are found now.
  Unfortunately, we have to distribute the entire Adwaita icon theme
  as distributing only the scalable (SVG) icons does not work for some
  strange reason (FIXME).
