Re: Session cancellation and reconnection

I have created a pull request that conveys the suggested specification for
automatic session reconnection.

https://github.com/webscreens/presentation-api/pull/23

Please note that there are some open issues that were added as I fleshed
out the specification:

* If more than one presentation session exists with the same url and
presentationId (on different screens) then what is the behavior of
joinSession(url, presentationId)?

* If the user agent becomes aware of a presentation session after the page
has already called joinSession, there is no way to notify the page of its
existence. Should we use an event handler instead?

* If the page calls startSession(url, presentationId) with the same url and
presenationId as joinSession(url, presentationId), and the latter call has
not resolved, behavior is not defined.

* Since we permit multiple opener pages to connect the same presentation
page, we need to define how connection and disconnection of these pages is
communicated to the presentation page (if at all).

I'll open these up for discussion, perhaps we can resolve some of them to
make the spec more solid.
