SVN commit 494037 by mwiesweg:

digikam from trunk: Threaded image loading

- Fix LoadSaveThread
- Add a class DImgLoaderObserver which allows communication with the loading/saving in a different thread:
  - progress info
  - stopping hooks to abort the loading/saving process
- Add a class ManagedLoadSaveThread which manages the tasks in its queue and allows preloading.
  To achieve this, it uses the stopping capabilities in the loaders
- Added progress info and stopping to JPEG, PNG, TIFF, PNG loaders, added progress info to raw loader.
  QImage loader does not support this.
- Use new ManagedLoadSaveThread and connect progress info to histogram tab

TODO:
- add preloading to DImgInterface and thus to IE and showfoto
