Invalid gravatar prefetch URI

[Dreyer]

The link for gravatar looks incorrect. Can anyone confirm?

https://github.com/ademilter/SocialCrumbs/blob/master/dns-prefetch.php#L13

<!-- gravatar photo -->
<link rel="dns-prefetch" href="//https://1.gravatar.com">

Looks like it should be:

<!-- gravatar photo -->
<link rel="dns-prefetch" href="//secure.gravatar.com">
<link rel="dns-prefetch" href="//www.gravatar.com">
