move controller to outer level, otherwise headings won't get displayed
Various smaller fixes

* new promisetracker requires explicit call to .regsiter and .deregister
* location of hmtl-files on github changed, fix
* do not collect links in info-Records displayed on check detail area
* dynamically set the url parameter when clicking on an item in the grid.
  Still missing: position on matching item when called using an url-parameter
