Add support for the Play Framework.

Not sure I'll get this into 0.7, given the number of bugs that have come out recently I may have to push out 0.7 sooner than I thought. Removing from 0.7 milestone for the time being.

@sapessi whatever happened with this, is play support still on the todo list?

Hi @jannylund. Yes, this is still on the todo list. I'm a bit concerned on the cold start time for Play. We'll take a look at this soon.
