Total Items is 1 even if there are no rows

Kogrid will display total items of 1 in the footer even if the number of rows in the grid is 0. I think I have nailed it down to this piece of code:

``` javascript
self.maxRows = ko.observable(Math.max(self.config.pagingOptions.totalServerItems() || self.sortedData().length, 1));
```

Why is maxRows defaulted to 1?

Search the KoGrid codebase for the maxRows assignment shown in the issue and trace how it feeds the footer's total-items display. Reproduce an empty grid, then verify that the footer reports zero items without changing the behavior for grids containing rows.
