Title: Updated bugsnag README.md for Bugsnag.beforeNotify example.

I couldn't find beforeNotify in bugsnag-1.0.9.min.js. Also, when I used the example for beforeNotify, I noticed that it would return null, at least in Chrome and Safari on mac, which would mean retVal === false would never equal true on line 246 on dist/bugsnag.js in this example.
