event.preventDefault() for links in Opera

[sgtpep]

I began to test my angular application in recent Opera (12.00, OS X) and found that clicking the links without href attribute does not always prevented, so it messes up navigation. Adding the "return false" fixes the issue to me.

@sgtpep if you can provide a test case for opera that shows the buggy behavior, we'll fix it in a different way.
