Problems with the use of $ in yourt Plugin

Hi, I recently stumbeled over an issue with your plugin. On the index.php on line 107 you used the following jQuery code:

$('.wpcf7').on('mailsent.wpcf7',function(e){
        var id = $('.g-recaptcha-explicit-id', this).val();
        $('#' + id).html('');
        grecaptcha.render(id, {
            'sitekey' : '<?php echo $this->site_key; ?>'
        });
    });

This produced an arreor in my modified twenty fifteen theme. You probably should wrap this function like so:

( function( $ ) {
		$('.wpcf7').on('mailsent.wpcf7',function(e){
			var id = $('.g-recaptcha-explicit-id', this).val();
			$('#' + id).html('');
			grecaptcha.render(id, {
				'sitekey' : '<?php echo $this->site_key; ?>'
			});
		});
	} )( jQuery );

or just use jQuery instead of $. Hope that helps someone.
