Create required dirs:

mkdir ~/.pow # where play will register the http.port
mkdir ~/.nginx-sites # where pow will create proxy configs

Tell nginx to load sites config from your ~/.nginx-sites by adding this to /etc/nginx.conf:

	import scala.concurrent.duration._
	import scala.concurrent.ExecutionContext
	import scala.concurrent.Future
	import akka.pattern.after
	import akka.actor.Scheduler

	/**
	* Given an operation that produces a T, returns a Future containing the result of T, unless an exception is thrown,
	* in which case the operation will be retried after _delay_ time, if there are more possible retries, which is configured through
	* the _retries_ parameter. If the operation does not succeed and there is no retries left, the resulting Future will contain the last failure.
