Allow user to copy script tags also

[bobsilon]

Hey there, Using textarea instead of span will allow us to use script tags in our copy string as below:

<script type="text/javascript">
    !( function( w, d ) {
        'use strict';
        var awesome = 'ngClipboard';
        console.log('Something awesome: ');
        console.log(w);
        console.log(d);
    })( this, document );
</script>
