Use gimp_image_get_layer,channel,vectors_list() instead of gimp_image_get_layer,channel,vectors_iter(). As a side-effect, simplified some code that was making sure we don't modify the list returned by the old functions (the new functions return newly allocated lists so we can safely remove items from the image while iterating it). Some places will need adjusting once we really have item trees.
