io.bind: XMLHttpTransport Error: 1223 Unknown (Internet Explorer bug)

[alain DOT! odea AT! gmail]

This is technically an IE bug, but since it's extremely unlikely that the agile giant will actually fix it I'm posting it here.

Sometimes IE translates HTTP 204 (No Content) into its own internal Status Code 1223. This causes BrowserIO to indicate an error condition in the response.

Status Code 1223 appears to be related to user-cancellation of requests. It appears on MSDN related to canceled Shutdown requests.

I patched this in my own environment by adding another allowed http.status to doLoad().

Here is my patch:

the fix looks odd, but workable. I'm marking it for 0.4.3 inclusion.

Do we have any idea which versions of IE are affected by this?
