remove executable bit from these non-executable plain-text files (relevant only on *NIX systems)
only show the rating inputs if the user is registered.
- removed unnecessary injection of DialogService into Details Controller
- removed console.log() statements from RatingService
- removed confusing USER_TOKEN parameter from REST-URL in RatingService (only in commented code)
Merge pull request #77 from SchweizerischeBundesbahnen/feature/mfr/rating-only-registered

Ich sehe noch file mode changes => 100644. (nicht mehr executable?). Gehe aber davon aus, dass es passt.
