[oslc-core] Problem in Delegated UI Window Name protocol example

[Dave]

Jazz developer Matt Jarvis just pointed out that our Delegated UI
example for Window Name Protocol does not work properly on IE.
Apparently, setting frame.onload = function() only results in an event
on Firefox. For IE, we may need to use the IE-specific
iframe.attachEvent instead.

I propose that we modify the example so that it checks for IE and does
the right thing.

Any objections to that?

Thanks,
