Where is what: updated Plone CSS and templates doc for v3

As an update to Quick Plone visual customization: I’ve just finished overhauling Jet Wilda’s “Where is what” tutorial on Plone.org, which has been written up by Christian Scholz (and subsequently on Plone’s Planet Plone site). The document is still lacking a few bits regarding CSS elements and templates for Plone v3, but it’s a bit better off than it used to be.
