Update socket intialization logic to handle ws:// and wss:// application transport

[shulard]

I've refactored some objects in the Hoa\Websocket lib and I've added :

• new Socket extension to deal with application transport ;
• new Connection extension to deal with the new Socket implementation ;
• new Handler name to be more precise regarding to Hoa\Socket implementation

The following code allow me to connect to a websocket server :

<?php
use Hoa\Websocket;

$url = "wss://examplehost.com";
$endpoint = "/";

$connection = new Websocket\Connection($url);
$client = new Websocket\Client( $connection, $endoint );
$client->setHost('hoa-project.net');

$client->connect();
var_dump($connection->isConnected()); //bool(true)
$client->close();

This PR is related to :

• hoaproject/Websocket#41 => Implement the isSecured checked to enable encryption
• hoaproject/Websocket#44 => Refactor part of the logic to be more accurate with Hoa\Socket
• hoaproject/Socket#26 => Implement the application transport handling at Websocket level to let the Hoa\Socket layer as generic as possible.

Also linked to already pushed PR hoaproject/Socket#27 which is a draft about Socket wrapper implementation.

Not the way to that correctly. See hoaproject/Socket#27.

Not the right way to do that. I close that PR and must create a new one which include the last work on Socket lib.
