Subject: [PATCH] Block encoded thumbnail URLs ('data:image')

These only work in the `selectThumbnail` component. If it's small enough, it'll get past the transaction limit-check, but ultimately it doesn't appear correctly in the claim list.

It'll probably appear correctly if we tweak the ClaimPreview code, but since this also fails the Google Video metadata test, I think we should disallow this.
