Title: WIP: Support clicking into a tree ring

This patch provides the functionality to support clicking on a tree ring and have a lightbox open to a single row heatmap for the given pair. Based upon the configuration of the `div`, this can also be reconfigured to redirect to the appropriate page - allowing for variations on how the widget is used.

At this stage, the pair related functionality works, but the time range selected is ignored. Presumably, we'll want to support opening the heatmap and difflist to the right place as well.
