In r183023: <http://trac.webkit.org/changeset/183023>, mixed content blocking was disabled for WK1 clients. This is also needed for our Windows clients: 1. If the preference is set to block (or allow), we honor that setting. 2. If the preference has never been set, we allow mixed content to match existing behavior. Security-Conscious WebKit Windows clients should be sure to set this preference to FALSE in new applications.
