Display actual link HREF instead of "javascript:void(0)"

[pdehaan]

Seems to be coming from /src/privileged/blurts/FirefoxMonitor.jsm:

https://github.com/mozilla/blurts-addon/blob/f7cadaa735be547648b191ba05496b7b32495228/src/privileged/blurts/FirefoxMonitor.jsm#L299

I think we can possibly use this as a workaround, where we set the <a href=""> to the str.link, and then make sure we call event.preventDefault() in the click handler.
