----------------------------
Hi,
MultiValues are not stored for any metatags in the HTML and any metatag can
have multiValued fields too.
When we use Tika for parsing with Nutch, we noticed that Tika does not store
the multiValues for any html metatag. Tika only places one value in the DOM
tree as reported in NUTCH-1467.
Does this patch allow Tika to have multiValues for any metatag or just
OpenGraph metatags ?

> HtmlHandler should use Metadata.add() for Open Graph properties instead of
> the HtmlHandler.addHtmlMetadata() method which uses Metadata.set(). The og:*
> properties can be multivalued. The Metadata.set() method overwrites previous
> entries because it doesn't use Metadata.appendedValues().
