Improve the Legends of the DataTableView

[mkommend]

It should be customizable which DataRows are shown in the DataTableView not only by clicking on the corresponding legend item but in addition it should be configurable in a dialog displaying a CheckedItemList (similar as hiding colums in the StringConvertibleMatrixView).

Another useful feature would be to hide all legend items, which can get quite annoying when dealing with lots of DataRows.

My 2cents:

If you're integrating this into the DataTableVisualProperties I think you should add this to the configuration dialog that we already have. I think the view that displays all the rows there is already a TreeView or ListView because it also displays icons. You just need to add select all/none options.

Or maybe we can make it so that by default we always only display the first 10 DataRows and provide some kind of "..." item/label/button next to the legend which can be pressed to show 10 more (or the next 10, or all).

It has been decided that this feature is not necessary.
