Subject: [PATCH] New: Number formating helper

- I've come accross a lot of cases recently where numbers need to be
  formatted for display, so I wanted to introduce rendering helpers for
  DataTables to make this easier. Only one helper introduced here -
  `$.fn.dataTable.render.number()` which will return an object that can
  be used by `columns.render` to format "raw" numbers.

+	 *   * `string` (optional) - Prefix.
