Update Polymer to v0.0.20131107.
Avoid flexbox on the title page; it's not widely supported enough yet.
Add a way to publish a static HTML version of the TS.

This only works with the polyfill ShadowDOM, so I've checked in a published
version generated from Firefox, which doesn't have a native implementation.

I put the 'publish' button at the very bottom of the dynamic page, where
hopefully it won't get in the way.
