Homepage update

Mostly format changes this time--chopped the main Rhomaioi page up into
chunks, properly linked the Kra'Vak design sequence page (not the one agreed
to on this list), and the various Islamic Federation & Saeed Kaliphate pages
(latter with credit this time), expanded the timeline somewhat, focusing on
adding "big picture" to show NRE in context. Expanded the Foreign Relations
bit, but not much.
