symposion_app/cms_pages/models.py
Nick Seidenman (N6) 6121ce79cc Getting the splash homepage to work via CMS.
Nearly there.  Much rubbish / cruft ripped out of  site_base.html and content_page.html.
Had to modify cms_pages/models.py to accommodate a "simple" layout option in the homepage
editor.
Still some stuff to do.  Styling not quite there yet, but want to checkpoint this.
