Blog title appears twice in tag

Hello, many thanks for this great theme. I have just installed it on my blog which has been recently upgrade to WP 4.2.

I noticed the blog title was being output twice in the <title> tag of every page. After some investigation, I noticed on line 103 of the functions.php file, you have this:

// Add the site name.
$title .= get_bloginfo( 'name' );

I was able to resolve the issue by commenting that line, which concatenates the existing title with the same again, hence leading to the issue.

Please let me know if you require any more information.

Thanks!
