fotoxx 8.6

An automatic white balance function was added. The success rate for 1-click red-eye removal was raised from 47/54 test cases to 52/54 (drag method is 100% successful but needs more time and care). Convience buttons were added to the HDR final adjustment dialog. A Spanish translation was added for the User Guide "quick guide" section. Bugfix: Image navigation could crash if presented with an empty folder. Bugfix: Zoom-in followed by some edit functions caused the image to be displayed with a false width/height ratio (cosmetic only - edit still worked normally).
