HACKING: Add required reading section & commit should give full rights details

* HACKING.tex: (COMMIT MESSAGES) It's pretty critical that commit messages
  give all the detail required to figure out what authorship/copyright
  claims might come into play.

  (REQUIRED READING) Add a section on what people are implicitly agreeing to
  when they contribute.  It's fairly obvious, common sense stuff.  Spell it
  out though.  Note that COMMIT MESSAGES are also required reading.

  (Cover page) Draw attention to REQUIRED READING.
