Time: Removed graphFormat

setFormat no longer defaults to the value of graphFormat optionally set in
controlDict and must be set in the functionObject dictionary.

boundaryFoam, financialFoam and pdfPlot still require a graphFormat entry in
controlDict but this is now read directly rather than by Time.
