	* DataGrid.cs: when paging is enable, the actual number of items is not
	the number of items rendered before the postback, but that number times
	the number of pages. Now we store the page count in the viewstate. Also,
	as the number might be big, don't allocate an array of objects to fake
	the collection for the PagedDataSource, but use the new NCollection
	class instead, which provides cheap (memory wise) enumerator for an
	arbitrary number of items. Thanks to "Adriano" for the test case.
