Move content element previews belonging to css_styled_content to this extension
For the strong default in "frontend" some content elements, like "text", "textpic" and "image", have been moved to css_styled_content. The content previews for these elements in the page module are still handled by "cms". This should move to "css_styled_content".
[TASK] Isolate content element previews for page module
With the new strong defaults some content elements have moved to
the extensions mediace, css_styled_content and compatibility6.
The previews for the page module have not been moved.
This patch moves some previews to the corresponding extensions.
