Fixed AR-822: Space deletion via FTP or Web Client is improved.

The node is renamed and hidden from FileFolderService clients.  A background task then performs the archival.
A bootstrap component ensures that failed archivals are picked up again.
Found a bug with the status of nodes archived as part of a hierarchy not being updated correctly.
