After setColumns selected class is not applied to new columns

[Crisfole]

Applies to grids with RowSelectionModel:

Steps to Reproduce:

1. Open http://mleibman.github.io/SlickGrid/examples/example9-row-reordering.html
2. Open Console
3. Enter the following Commands:
   1. grid.setSelectedRows([0])
   2. cols = grid.getColumns()
   3. cols.push({ id: "TEST", field: 'name', name: "TEST" })
   4. grid.setColumns(cols)

Expected Output:

• Whole selected row is highlighted, including new column.

Actual Output

• Original columns in selected row are still highlighted. New column isn't.

I had a similar problem. You need to call the following after adding columns:

grid.setSelectedRows(grid.getSelectedRows())

Yeah..I did that, but I think it should do it automatically
