Subject: refactor list of data sets out of GraphWidget into a global data
 structure.

Also, add a sigc signal for broadcasting data set changes.

* grapher/GraphData.hxx (GraphDataList) new typedef
  (getGraphData, graphDataSignal): new functions
* grapher/Graph.hxx (DatasetList): remove typedef in favor of
  systemtap::GraphDataList
* grapher/GraphWidget.cxx (GraphWidget, onGraphDataChanged): Use
  graphDataSignal to notice new data sets that need to be added. Use
  the global data set list instead of one embedded in GraphWidget.
* grapher/StapParser.hxx: delete the _widget member; use signals to
  broadcast that there are new data sets instead of calling into the widget.
