fix(react-grid): optimize table selection rendering

[SergeyAlexeev]

Fixes #397

[DanHarman]

@SergeyAlexeev Not sure if this fix is published yet, but I see the whole table redraw on row selection regardless of 'highlightSelected' being set on the TableSelection? So even though rows remains the same the whole virtual table will redraw on row click, rather than just the affected rows.

<Grid getRowId={getRowId} rows={this.props.orders} columns={ColumnDefinitions.columns}>
    <DateTimeTypeProvider />
    <SortingState />
    <SelectionState selection={[this.props.selection]} onSelectionChange={this.handleSelectionChange} />
    <LocalSorting />

    <VirtualTableView />

    <TableSelection highlightSelected selectByRowClick showSelectionColumn={false} />
    <TableColumnResizing defaultColumnWidths={ColumnDefinitions.defaultColumnWidths} />
    <TableHeaderRow allowResizing allowSorting />
</Grid>

Is this intentional as the click handling seems a little slow.

Yes, there are some recalculations because of the react diffing algorithm. But, it should not cause any performance issues. We tested the scenario you described with a huge amount of data and it works sufficiently well. If you have a sample that works inadequately, please provide us with it.
