Add ActiveRowStyle property

[CodingBlob]

As in WPF DataGrid the DataGrid should have a RowStyle property where the style for a row can be defined:

We already offer custom CellTemplate abilities on a per-column basis. And we allow customizing the RowsTextColorPalette and RowsBackgroundColorPalette using any object that inherits from IColorProvider. This allows you to make patterns based on the row order. And we allow customizing the color for the selected row via the ActiveRowColor property.

As such, I think there isn't much more that we need to provide.

If you provide a more complete proposal for exactly how and why this is needed, over and above the features we currently offer, then please open a new issue.

Also, pull requests are welcome.

I wanted to highlight rows based on a search text with a border around the row. As far as i know this is currently not possible.

I suppose an ActiveRowStyle may be possible. I will leave this open for future consideration and PRs, but don't plan to do this myself at the moment.
