Dive pictures: change removePicture() interface

Browse source 
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.
