Language Chooser on Calista

The language chooser in Calista sometimes did not work as expected. It was not able to switch to the same commerce page in a different language, e.g. on search results page. To avoid dead links, the language chooser in the Calista demo site and templates now always links to the hompage of the derived locale specific sites, regardless what content is currently displayed. This only affects projects if they use the out of the box PageGridPlacement.asHeader.ftl template.
