This patch hides a picture from the dive, it should actually remove it, but because I didn't found a quick way to remove a picture from the dive yet, it just hides it. To remove a picture from the dive, the DivePictureItem has to remember the QUrl of the original file, to remove that from the model, and currently it only has the QPixmap. this can be for 4.2.1 or we can postpone 4.2 a tiny bit since this is a important feature.
