The function removePicture() had a flag "last", which would indicate that the called had finished removing pictures. Only then would the model be recalculated. This is a strange interface and, matter of fact, the caller was buggy: if the last picture to be removed didn't have a proper url, removePicture() was never called with "last" being set. Change the interface to take a list of pictures to be deleted. This will allow us to make picture deletion smarter in follow-up commits. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
