modified jquery.prettyembed.js to allow multiple instances

[sethbrasile]

Added:

$(this).attr('id', thisVideoID);

Just after:

if ( $(this).attr('data-pe-videoid') !== undefined ) { thisVideoID = $(this).attr('data-pe-videoid'); }
        else if ( $(this).attr('href') !== undefined ) { thisVideoID = youtube_parser( $(this).attr('href') ); }
        else { thisVideoID = options.videoID; }

---

Changed:

$(this)

To:

$(e.target)

In:

 $('body').on('click', '.pretty-embed', function(e) {
        e.preventDefault();

        clickEventRunner( $(this) );
    });

Because it seemed like this was working in the wrong context.

Changed:

else if ( options.videoID !== undefined ) { thisVideoID = options.videoID; }

To:

else if ( obj.attr('id') !== undefined ) { thisVideoID = obj.attr('id'); }

In:

if ( obj.attr('data-pe-videoid') !== undefined ) { thisVideoID = obj.attr('data-pe-videoid'); }
        else if ( options.videoID !== undefined ) { thisVideoID = options.videoID; }
        else {
            thisVideoID = undefined;
            console.error('PrettyEmbed.js Error:  Misformed or missing video ID.');
        }

To set video id from 'id' attribute that was added earlier.

I did not check for other use cases (such as the "HTML5 Driven Application" example).
