#1616: Remote CSS: Allow data URIs in CSS properties

 I'm using the Remote CSS feature for WordCamp Boston. I'd like to use SVGs
 for background images, encoded directly into the CSS file using [https
 ://css-tricks.com/data-uris/ data-uris]. Unfortunately, the sanitization
 for URLs in the `jetpack-tweaks` sees this value as a URL, and strips
 `data:`, thinking it's a bad protocol. You can see it's broken on
 [https://2016.boston.wordcamp.org boston.wordcamp.org], the white
 rectangle should be our logo.

 I've attached a patch which just adds `data` as a valid protocol, but I'm
 not sure if there are any reasons we might not allow that (security comes
 to mind, but if we allow any http url...?).
