- Features:
    * Make ->distinct_column_values use ->simple_query, thus going through our
      SQL logging infrastructure (Alex Vandiver)

    * Respect the 'by' attribute for refers_to columns in create and set
    * Use the right FK when using a record object in load_by_cols or

    * Don't encode fields when attempting to limit with IS
    * Fix since/till by refactoring columns to use an updated all_columns
