PUB-72: ported cliff's fix from cliffc-str branch to master.
2 changes to enum parsing:
    a) do not skip double quotes (escaped quotes in csv format, e.g. ""txt"" should be "txt" but we keep the double quotes.
    b) do not transform ValuStrings into Strings (potentially lossy conversion) until we're done with parse, so the sec on stage (or enum update in case of parse2) are performed directly on ValueStrings. Domain is still stored as java String array though.
