color: add additional changeset.phase label to log.changeset and log.parent

This allows the user to set different colors for each phase, e.g.

[color]
changeset.public = blue
changeset.draft = green
changeset.secret = red

In addition, this doesn't affect current configuration for custom log.changeset
colors, but rather adds the option for users that want to visually see which
changesets are amendable.
