[Setup] Change site_icon in navigation tree

[danielle davout]

with Firebug you could see that the class of the link at the top of
the navigation of the whole tree is contenttype-plone-site
in the portal_skins you can find all the elements that content
"contenttype-plone-site"
There in public.css you have ..
.icons-on .contenttype-plone-site {	
	background: no-repeat transparent 0px -1508px url(contenttypes-sprite.png)
