We make it easier for users to correlate between 128-bit node
identities and 32-bit node hash by extending the 'node list'
command to also show the hash value.
We also improve the 'nametable show' command to show the node identity
instead of the node hash value. Since the former potentially is much
longer than the latter, we make room for it by eliminating the (to the
user) irrelevant publication key. We also reorder some of the columns
so that the node id comes last, since this looks nicer and more logical.
