String appended to network-wide Favicon URL circumvents CDN cache

Hi there.

When Custom Multisite Favicon feature is enabled, the favicon does show across the network, but not exactly the URL I specified in Ultimate Branding settings.

There seems to be a unique string appended after every favicon image URL generated network wide by Ultimate Branding - looks like this:
http://xxxmyblognetworkxxx.com/wp-content/uploads/2015/12/thefavicon.ico?d42c842b4ae671f877a430a6a22324f6

That string circumvents our CloudFlare cache and causes our server to be hit with every single favicon call directly.

Could you disable this string and show the image URL exactly as specified in the Ultimate Branding images screen so that it's served from our CDN and cached for all subsequent displays. :slight_smile:

Thanks!
