Install and distribute gnome-shell.css and theme images. They are moved down from $datadir to $datadir/theme to avoid a weirdness where we have images in $datadir and then also in $datadir/images. (Also moved in the source tree to avoid adding another difference between installed and uninstalled operation.) https://bugzilla.gnome.org/show_bug.cgi?id=595989
