Due to refactored directory structure (and hence PHP namespace changes) templates now have to use (e.g.)
Fiedsch\LigaverwaltungBundle\Model\HighlightModel as opposed to \HighlightModel which was used in
versions < 1.0 where the models lived in the Contao namespace. Affected templates are
ce_highlightranking.html5 and ce_spielbericht.html5.
