SAK-12563

Switch sakai.iframe.site.xml to be rendered as a portlet

This change requires two related JIRAs to fully function

SAK-23224 - Wrap portal markup in a floated left div (Coming from Gonzalo)

SAK-23195 - Add CKEditor support to JSR-168 Portlets (Coming from me)

I will wait to do the merge until these have landed in trunk.  I will let
Gonzalo commit SAK-23224 first then I will commit SAK-23195.
