Demo pages organization

This issue is a minor suggestion about the demo pages organization. It seems that the module application-interactive-maps-demo is not used by the demo map, and does not add significant demo aspects. What about removing this module altogether?

Regarding the demo pages: at the moment, they are splitted into several spaces, some of which do not contain a "WebHome", which can be confusing for the user when navigating via the breadcrumbs. We may consider either adding a WebHome to each space, with some content, e.g. a list of the pages contained in that space, or moving all pages to the "Demo" space itself. Even though they contain various objects on several topics, they serve a common and single purpose in this context: the Demo map. What do you think?
