ExtendedDbDataReader Class

Marking wrapper for DbDataReader. Replaces the function of the IsFromCMSDatabase(DataTable, Boolean) method and TABLE_IS_FROM_CMS_DB in DataTable's extended properties.

The TrackExternalData(DataTable) and TABLE_CONTAINS_EXTERNAL_DATA members do not need a replacement as data reader does not allow for modification of its values (unlike DataTable).
