Add support for EXT:news description field

[AstCommodore]

Please add support for the field EXT:news->description as it is used in tx_news 2.2.4 in partial Opengraph.html:

<f:if condition="{newsItem.description}">
    <f:then>
        <n:metaTag name="description" content="{newsItem.description}" />
        <n:metaTag property="og:description" content="{newsItem.description}" />
    </f:then>
    <f:else>
        <n:metaTag name="description" content="{newsItem.teaser}" />
        <n:metaTag property="og:description" content="{newsItem.teaser}" />
    </f:else>
</f:if>

In MetatagPart.php there is a routine to setup the field news->teaser as meta:description, so something like this should added here:

if( isset($GLOBALS['TSFE']->register['newsDescription']) ) {
            $connector->setMetaTag('description', $GLOBALS['TSFE']->register['newsDescription']);
        } else {
            if( isset($GLOBALS['TSFE']->register['newsTeaser']) ) {
                $connector->setMetaTag('description', $GLOBALS['TSFE']->register['newsTeaser']);
            }
        } 

But this is only half the way. I'm not deep into the code, maybe it's possible for you to add this feature easily.

Greetings, André

please also add support for other news "meta" fields like the news "alternative_title" field for example!
