Chart.Grid multiple bugs

[kMutagene]

Chart.Grid has, while being a great improvement over the old Chart.Stack, multiple things that need fixing:

• Charts are added to the Grid in reverse order
• Grid attributes dont work as expected (e.g. Roworder not changing anything)
• Not truly any trace can be a subplot of this grid so far. Examples are Chart.Table or Chart.Histogramm2DContour. Most likely because the usual way of setting subplot domains does not work for these trace types.

should be fixed with the next release.
