The code of DivePictureModel used a QHash to keep track of thumbnails. Not only was the code rather complex - it also had the consequence that pictures are sorted according to the hash function, i.e. seemingly random. This commit replaces the QHash by a simple QList which keeps track of thumbnails and some meta-data. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
