Smart Content (provider "pages") should return the nodeType of the nodes

[thomasduenser]

When using the smart_content type, the response doesn't contain the nodeType of the child pages. This would be helpful to open those pages e.g. in a new tab.

Tested with following example:

<property name="smartContent" type="smart_content">
            <meta>
                <title lang="de">Smart Content</title>
                <title lang="en">Smart Content</title>
            </meta>
            <params>
                <param name="provider" value="pages"/>
                <param name="categories_parameter" value="c"/>
                <param name="website_categories_operator" value="AND"/>
                <param name="properties" type="collection">
                    <param name="excerptTitle" value="excerpt.title"/>
                    <param name="excerptCategories" value="excerpt.categories"/>
                    <param name="excerptImages" value="excerpt.images"/>
                    <param name="headerTitle" value="headerTitle"/>
                    <param name="headerImage" value="headerImage"/>
                </param>
            </params>
        </property>
