Prevent selection of single row

[JockeLindberg]

Currently, you can prevent a complete selection action (which can contain 0-all rows).
Make it possible to prevent a single row from being selected.

We already have the isSelectable API on GridSelection. Either use that or make it possible to maniupulate the array of records which is about to be selected through use of the beforeSelectionChange event.
