Cell rendering in DataGrid columns has been updated to allow the cell
to override the DataGrid's choice of cell template. This allows the
the CheckboxColumn to render without links, which would previously
activate when checked.

Tested the change with Review Board. There were no links in the
dashboard's checkboxes. Checking the checkbox did not redirect before
and after switching into mobile mode.
