Goal: have an interactive chat (html-only implementation)

The first iframe should display _all_ the posted messages, always
scrolling to the bottom and refreshing every 1-2 seconds.

The second iframe should take user input. It should post the message
to the chat (write to DB) and redirect back so that the user can type
another message.
