Start fixing #214 - workaround for bug in IE8 iframe onload implementation

IE8 doesn't honour onload listeners attached using Javascript. See:

    http://stackoverflow.com/questions/12910534/why-doesnt-ie8-handle-iframe-onload-events

This commit attaches the handler using HTML instead.

A further commit will be needed to reorder the code to avoid a race condition
where the iframe is initialized before the handler is setup.
