Frederic Massart f1b93a70bf MDL-42666 repository_boxnet: Convert repository to APIv2
The support for downloading images when they are references
from Box.net have been dropped in this script as the new
API does not support references. Unfortunately the old
references thumbnails will not be updated any more.
