Add the ability to specify a default MIME type when loading a resource. We'll need this to correctly load stylesheets that lack a Content-Type header in standards mode.

We're waiting on https://bugs.webkit.org/show_bug.cgi?id=24904 upstream before this works fully.  This change, as it stands, is a no-op.
