Org reader: respect `creator` export option

The `creator` option controls whether the creator meta-field should be
included in the final markup.  Setting `#+OPTIONS: creator:nil` will
drop the creator field from the final meta-data output.

Org-mode recognizes the special value `comment` for this field, causing
the creator to be included in a comment.  This is difficult to translate
to Pandoc internals and is hence interpreted the same as other truish
values (i.e. the meta field is kept if it's present).
