BUG: inconsistency between constructor and output (fixes #1816)

- slipped in with changes to csvTableReader (commit 59ed3ba18d) so
  only affects the 2006 version.

- adjust constructor to expect "componentColumns", but also accept
  "valueColumns" as 1912 and earlier-compatibility. This not only
  fixes the reported bug, but also ensure proper compatibility with
  older files.

ENH: use "refColumn" instead of "timeColumn" for csvTableReader

- consistent with the CSV Function1.
  Support 'timeColumn' as 1912 and earlier-compatibility.

TUT: remove unused table-reader entry
