Attribute and params support for the iframe embed code

[microstudi]

Hey, great class here.
When I was using your class I realized than the iframe embed code cloud not be customized so I modified the code in order to do so.

Now you can do something like:

if ($MediaObject = $this->MediaEmbed->parseUrl('http://www.youtube.com/watch?v=111111')) {
    $MediaObject->setParams(array(
        'autoplay' => 1,
        'loop' => 1
    ));
    $MediaObject->setAttributes(array(
        'type' => null,
        'class' => 'iframe-class',
        'data-html5-parameter' => true
    ));

    return $MediaObject->getEmbedCode();
}

This should return and embed code like:

<embed src="http:/www.youtube.com/embed/111111?autoplay=1&amp;loop=1" class="iframe-class" data-html5-parameter></iframe>

I updated the main classes, tests, examples and README.md files
I hope you found it usefull.

Awesome stuff!!! 👯

[microstudi]

Sorry. Check it now!

[dereuromark]

Looks good to me :)

Should be fully BC should it not?

[microstudi]

sorry, BC? what do you mean?

[dereuromark]

backwards compatible, so it doesnt break existing stuff :)

[microstudi]

ah, yeah! no problem is fully compatible. By default it shows exactly as you did. You can check the examples.

In this case you dont need an else, since you return early.

[microstudi]

This is something from github, i don't have this "else"
https://github.com/microstudi/MediaEmbed/blob/master/src/MediaEmbed/Object/MediaObject.php#L346

[dereuromark]

Look at the line number beside it (316).
So you do here, though:
https://github.com/microstudi/MediaEmbed/blob/master/src/MediaEmbed/Object/MediaObject.php#L316
and
https://github.com/microstudi/MediaEmbed/blob/master/src/MediaEmbed/Object/MediaObject.php#L342

It's just a good coding practice to keep the levels to a minimum
returning early and avoiding elses does that.
