Test get, formatter, and renderCell

This page tests various responsibilities of renderRow in Grid.js, particularly those sensitive to dojox-grid-friendly properties.

## 1a: Grid with single column with formatter for _item field (legacy grid behavior)

## 1b: Grid with single column with formatter for _item field, using formatterScope (legacy grid behavior)

## 1c: Grid with single column with get for order field (legacy grid behavior)

## 1d: Grid with single column with renderCell function

(dgrid behavior; should look same as previous but with underlined first header cell and italicized first column values)

## 2a: Grid on domnode with no initial id, id specified as param (will become DOM node id)

## 2b: Grid on domnode with no initial id, dgrid / DOM node id autogenerated

## 2c: Grid with no srcNodeRef (placed inside another domNode), id specified as param (will become DOM node id)

## 2d: Grid with no srcNodeRef (placed inside another domNode), dgrid / DOM node id autogenerated
