component file sharing: comments handling first draft: comments use a minimal pubsub service which create virtual nodes for each files. A pubsub request to org.salut-a-toi.file_comments/[FILE_ID] allow to handle comments in classic way. Permissions are the same as for files (i.e. if an entity can see a file, she can comment it).

# FIXME: remove this when RSM and MAM are in wokkel
# XXX: the Monkey Patch is here and not in src/__init__ to avoir issues with pyjamas compilation
