Hi All,

In a recent call between Google and Mozilla we discussed some details
of how it would work when multiple parties wanted to join an
application running on the TV.

In that call consensus was that it would be good if the connecting
party could opt in to the ability to join an already running
application. So we would have two modes:

By default, when a session is start()ed, it always replaces any
running applications on the TV. If the existing origin is already open
on the TV, it shuts down the current page, disconnects any existing
session, opens the requested URL and establishes only the new session.

However, when the session is initiated, the initiating page can opt in
to enabling joining an already running application. If the application
is not running, then whatever application is running is shut down, its
connections disconnected, and the new application is started. But if
the application is running, then we simply fire the "sessionconnect"

We should probably enable this opt-in through an additional argument
to the PresentationSession constructor. We could also do it as an
additional argument to the start() function, but that would mean that
it can't be used for default sessions.
