[FEATURE] The addAnchor setting is now valued

Checking the checkbox "Add link anchor" in a fluidcontent_core provided content element had no effect.

This change results in an `a` tag being rendered at the top of the content element.
I broke the condition into:

		<f:if condition="{content.settings.container.addAnchor">
            <a id="{record.header -> v:or(alternative: record.titleAttribute) -> v:or(alternative: 'content {record.uid}') -> v:format.url.sanitizeString()}"></a>
        </f:if>

But this still ends up being 163 chars wide. I'm not quite sure how to convert any of that into inline notation to make it shorter. Please advise
