check for new parameter tt_news.single_page.*.keepListedAsPage to keep single view pages listed

tt_news single page views can now be optionally kept on sitemap.xml output (e.g. for dual-mode pages which contain both a LIST and SINGLE view on the same page and toggle the active tt_news mode based upon parameters passed on URL).

Can be used by setting keepListedAsPage as follows: (10 = your copy of plugin.tx_weeaargooglesitemap_pi1 on a PAGE TLO)


    10.tt_news.single_page {
        1 = {$newsPageContainingSingleView}
        1.pid_list = {$newsFolder}
        
        # list in sitemap.xml despite being a single page view
        1.keepListedAsPage = 1
    }
