  Changed paths:
    M HOWTO-make-a-release.md
    A HOWTO-publish-a-release.md
    A HOWTO-stage-a-release.md

  Log Message:
  -----------
  Reorganize the release HOWTO

This splits up HOWTO-make-a-release.md into two new documents that reflect
the fact that *staging* and *publishing* a release are really two separate
things.

This also reflects that we're working towards full automation for staging
releases.
