fix configuration for search page navigators

Browse Source 
- added additional config page (ConfigSearchPage_p) for easy setup of search page layout (to not overload ConfigPortal page)
   - currently redundant setting with part of ConfigPortal page
- added missing config for filetype and protocol navigator
- adjusted init of SearchEvent to check navigation config setting
- renamed RankigProcess.getTopicNavigator to getTopics (to distiguish between added SearchEvent.getTopicNavigator)
