place for wp5 deliverables

[retog]

Two others wp5 deliverables are in "overall architecture", should we move them here? Or move this one there?

@retog If you don't mind, I'd prefer if the others are moved here, for convenience. That way, we'll have all WP5 deliverables in one separate place, just as it is with WP1 deliverables and WP4 deliverables.
