First pass at converting scatter view to d3.

Original functionality replicated - now with user name hover, as well as click summary tooltip.

TODO:
* Replicate for timeline view.
* As all data has been retrieved through API, only refresh graph on axes change.
* Prettification.
Timeline view now switched over to D3.

Line plots highlight when appropriate legend is mouseovered.

TODO:
*Reduce y-axis options, and test all x-axis options.
*Integrate new activity reports into timeline.
*Use Raphael to give IE backwards compatibility.
Clean up of cruft.

TODO:
See last commit.
