Support for HTTP/2

[Playcorp]

Hi,

Can you update ApnsPHP with HTTP/2 connexion ? https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html

Thanks !

+1 ! Would be very nice to have the newer, simpler system. Of course its a big task - perhaps requires a new repo altogether.

I hope this helps, I haven't be able to test it yet (there is no support for HTTP/2 in Google App Engine yet)
