Show what a machine said it is made of in node, with its age (issue 160)

The architecture and kernel a machine reported were kept and read by nothing, and the facts the
node-engine now says (memory, filesystems, processor, distribution, virtual or physical, uptime,
timezone) would have joined them. node shows every one in one block with the age of the account,
and a fact the machine could not determine as unknown with its why, never as a zero.
