Basic ArchiveFilesModel and ArchiveController

Implement a new file model for the archive. It's quite basic at this
stage, but finally something happens when clicking the archive tree.

Also, implement the interaction (signal -> slot) between the views and
models in an explicit controller to prevent the mess from the old
archive.
