Make list of clients in a room accessible

[fodor0205]

I found it extremely useful to get the list of clients for a session / room.

This way I can access each socket with a forEach loop:

socketClients().forEach(function (s) {
    s.join('room');
});

I use send() to respond to the current socket with the callback.

Server side:

action(function join () {
    send({ foo: 'bar' });
});

On the client side:

socket.emit('join', {}, function (data) {
    console.log(data.foo); // bar
});

Sorry for combined pull request
