* lib/ipaddr.rb (<=>): Implement IPAddr#<=> and make IPAddr

comparable.

* lib/ipaddr.rb (succ): Implement IPAddr#succ.  You can now create
  a range between two IPAddr's, which (Range) object is
  enumeratable.

* lib/ipaddr.rb (to_range): A new method to create a Range object
  for the (network) address.
