Topic landing page configurable through conventional config sections

As the presentation for a topic, a landing page is created. this is handled by the addition of the filter. The landing pages can in turn be configured through config sections, similarly to the way regular sections are configured.

• http://www.mySite.com/topic/liverpool => config.topic.ece_frontpage will be looked up. If not found, config.topic will be used.

• http://www.mySite.com/sports/topic/liverpool => config.topic.sports will be looked up. If not found, config.topic will be used.

• http://www.mySite.com/sports/football/topic/liverpool => config.topic.football will be looked up. If not found, config.topic.sports will be looked up. If that is not found, config.topic will be used.

• and so on ...
