C. Scott Ananian 9dbce134c6 Allow ApiParse to use the ArticleParserOptions hook
Extensions can use the ArticleParserOptions hook to customize the
parser options used for article read views, and Visual Editor uses
ApiParse to regenerate the article read view HTML after edit.  In
order for VE to remain consistent with the original parse options,
provide a `usearticle` option to the parse API to allow it to invoke
the ArticleParserOptions hook.
