Summary:  fix to report errors in media loading

Details:

In the case of a server media error, the media loader calls returnData
twice, once from the testLoad loop,  when the image swf is loaded
(normal path), and
then if an error swf was actually returned by the server, it contains swf code
that calls returnData itself.

That second call was being ignored by returnData because it ignored
any loader which was marked as loaded.

This fix adds a check for non-null data being returned, and if so, returns
processes it.


Tests:

test/lfc/data/testhttpdata.lzx
test/lfc/data/alldata.lzx



This should report an error immediately in proxied mode


<canvas width="100%" height="80%" debug="true">

  <view resource="http://www.javawen.info/try/news_bg.png"

        ontimeout="Debug.write('ontimeout', this)"
        onerror="Debug.write('onerror', this)"
/>
