Fix: Portfolio custom links

Hi,

I think there should be a fix: Once portfolio items use custom links, the portfolio grid titles don’t include them.

Current code in portfolio.php:

if(!empty($title_link))
{
	$output .= "<a href='{$title_link}' title='".esc_attr(strip_tags($title))."'>".$title."</a>";
}
else
{
	$output .= "".$title."";
}

Modified version with custom links:

if(!empty($title_link))
{
	$output .= "<a href='{$title_link}' title='".esc_attr(strip_tags($title))."'>".$title."</a>";
}
else if(!empty($custom_link))
{
	$output .= "<a href='{$custom_link}' title='".esc_attr(strip_tags($title))."'>".$title."</a>";
}
else
{
	$output .= "".$title."";
}
