broadway: Initial support fro V7+ websockets

Allows more modern browsers eg. firefox 5+ to use gtk/broadway
Auto-detects protocol version, and can switch between them at
as you connect a different browser.

This works to some extent, but seems to hang sometimes, for
instance the "button box" test in testgtk never shows up.
