plugin comp file sharing: file sharing management first draft: the new "component file sharing management" plugin add ad-hoc commands to changes permission of one or several shared files, delete one or more files, or regenerate thumbnails. This is a temporary plugin to make file sharing through a component usable with other entities, but should be removed (at least permission management and file deletion) in the future if we move on a pubsub based solution.
