Release 2.2.0

[sb8244]

This is what my config for standalone PushEx looks like:

# config.exs

config :push_ex,
       PushEx.PubSub,
       adapter: Phoenix.PubSub.PG2,
       pool_size: 4

config :push_ex,
       PushExWeb.PushSocket,
       socket_impl: MyAppWeb.PushEx.Socket,
       endpoint: %{otp_app: :my_app, module: MyAppWeb.Endpoint},
       disconnect_sockets_on_shutdown: true

config :push_ex,
       PushExWeb.PushController,
       controller_impl: :not_implemented

# endpoint.ex

socket "/push_socket", PushExWeb.PushSocket,
    websocket: [timeout: 45_000],
    longpoll: false

• PushEx added to started processes, before my main app's PubSub process
• Normal setup otherwise
