I don't want to burden the component with too much properties.

So, I have implemented 2 methods:

1. The socket handler is now created in a virtual method:
    GetSocketHandler
    it can be overridden to implement custom behaviour.

2. There is an event OnGetSocketHandler which can be assigned to create the socket.
    the default GetSocketHandler calls this event, and if the event handler is not
    set or returns a Nil handler, it will create a default handler.

See if you can do it with this system, if not let me know what I would need to add.

Done, rev 27571.

Done, I have been staring myself blind at what could have caused this regression.
Thanks !!!
