Prototype of home page using web.py template feature (if successful, will update other pages as well.)

This rev of the home page is intended to test the following ideas:
- Templates will be a much easier format for web designers to use to
customize the UI (document.write is difficult to read, inaccessable to
tooling, and hides the basic structure upon which styling and behaviors
can be applied.
- Inline styles replaced by CSS statements (a step towards themable
stylesheets.)
- inline behaviors replaced by jQuery behaviors (a step towards more
dynamic behaviors, e.g. the clock now runs!)
