Version 1.12

What's Changed

• sunshine.8 man page updated. Rewrote it on RONN.
• --iid flag takes IPv6 bits which are put into the lower 64-bits of the
  generated IPv6, still uses PIO.
• --ipv6 option takes 128 bits which become the nodes' identity, PIO ignored.
• fixed a bug where a second route "below" the same adjacency was not installed.
  (How did this ever work?)
• fixed two uninitialized variable issue, one of which was mIgnorePIO!
