1.8.0

• Changed to PSR-4 autoloader
• PSR-1/2 code style fixes
• Removed some deprecated adapters: Cadenaser, Marca, Parleys, Rtve, Yfrog
• Changes in the Embed\Request class and Embed\RequestResolvers\RequestResolverInterface
• A lot of fixes and new tests
• Changed the way to configure the resolver. Now it's configured with the rest of the options under the "resolver" subarray:

//Old style:
Embed\Request::setResolverConfig(array(
    'userAgent' => 'My spider',
    'connectionTimeout' => 10
));

$info = Embed\Embed::create($url);

//New style
$info = Embed\Embed::create($url, array(
    'resolver' => array(
        "options" => array(
            CURLOPT_USERAGENT => 'My spider',
            CURLOPT_CONNECTTIMEOUT => 10
        )
    )
));
