app/widgets/gimpnavigationpreview.c renamed these files to ... 

* app/widgets/gimpnavigationpreview.c
* app/widgets/gimpnavigationpreview.h: renamed these files to ...

* app/widgets/gimpnavigationview.c
* app/widgets/gimpnavigationview.h: to these.
  And renamed the GimpNavigationPreview type to GimpNavigationView.

Hopefully, this is the last change in file names for the Preview->View
renaming process.

* app/display/gimpnavigationeditor.c

* app/widgets/Makefile.am
* app/widgets/widgets-types.h: Changed accordingly.
