#267 improved docu for breadcrumbs: documented meaning of breadcrumbId and where to define according breadcrumbs in app.js
#282 Display object names consequently without human readable
Only names for scenario and usecase is displayed as human readable (everywhere!).
Also not displaying object types as human readable.
Changed this in tree, on object overview page and in breadcrumbs.
(is now consistent with how it is displayed in metadata)
