Subject: Make the hover text conform to data displayed.

Start of code to be more selective about the association between the
hover text and the underling graph. Also, show the data set name in hover text.

* grapher/GraphStyle.hxx (dataIndexAtPoint): New virtual function.
* grapher/GraphStyle.cxx (dataIndexAtPoint): Implementation for bar graphs
* grapher/GraphWidget.cxx (onHoverTimeout): Use dataIndexAtPoint.
