Reports and statistics answer in ClientModels' shapes

The moderators' reports and the admin statistics (overview, hosts,
crawler) were anonymous objects, so a client could read them only as loose
JSON. They are now ViewReport, ViewStatisticsOverview, ViewHostsPage and
ViewCrawler in PrivaPub.ClientModels, with the same JSON as before, for
decePub's Administration page.
