Change data set list display to use a check box for inclusion in a graph

Incidently, this supports removing a data set from a graph.

Also, remove the Add, Remove, and Cancel buttons from the data set dialog.

* grapher/GraphWidget.hxx (DataModelColumns::_dataEnabled): new member
  _listConnection: new member
* grapher/GraphWidget.cxx (GraphWidget): Delete connections for
  removed buttons. Connect to dialog show and hide signals instead of
  map. Add "Enabled" column to dialog list.
  (onDataAdd, onDataRemove): delete
  (onDataDialogOpen): Initialize list store with all data sets and
  hook up row_changed signal
  (onDataDialogClose, onRowChanged): new functions
* grapher/graph-dialog.glade: Remove obsolete buttons (Add, Remove, Cancel).
