Little issues, combined commit!

- Bug #2857: Spin didn't create nice consistant normals
- removed unnecessary call to where_is_object() in init-render phase.
- Added DAG_scene_sort() calls when objects were removed (join cases)
- When using texture fonts, the file window header didn't display OK
- Saving a file didn't set the 'wait cursor' anymore (oldie!)
