Title: bubbleChart: set opacity on circles during render instead of <g> element

I noticed a small bug where r/opacity attributes were being set on the element instead of the circles themselves and I thought it was worth contributing back. I didn't see any bubbleChart tests in /spec, so I just added a simple vows test instead - hope that's okay. Please let me know if I need to do anything else, and thanks for a great library!
