Local files should not be allowed to read pasteboard data during drag

[Alexey Proskuryakov]

As implemented in <http://trac.webkit.org/changeset/6840> for Dashboard, local files are allowed to read pasteboard data during drag, while normal documents can only do that during drop even handling.

Even local documents should not be allowed to sniff content simply dragged over them, they are not that trusted. I'm going to make this a Dashboard quirk instead.

Missing indentation here. I normally find that this:

    <long line>
        ? x : y;

Is more readable than:

    <long line> ?
        x : y;

But the code above is:

    <long line> ?
    x : y;
