Play 2.8.x support

[solnaranu]

Hi,

is there any chance for supporting Play Framework 2.8.x? Several concepts which were deprecated in 2.6.x have been removed/refactored in 2.7 or 2.8. and atmosphere-play cannot be used with 2.8.x.

@solnaranu I don't have the cycle right now, but if you have the time I can review your pull requests, tests and release the new version.

@jfarcand thx for the quick reply.

I'd be very glad to contribute, but I would need to get much more familiar with atmosphere-play and Play to be able to pull it off. Also, my cycles are pretty tight too at the moment :)

Biggest problem I see is that play.mvc.Controller no longer has request(), response(), session(), so AtmosphereController and some other code like PlayAsyncIOWriter need to be a bit refactored/redesigned. Some info at Play 2.7 HttpContext Migration.

If you have some pointers on where to begin, it might set out a path to a useful contribution.
