joeduffy 7f0a97a4e3 Print configuration variables; etc.
This change does a few things:

* First and foremost, it tracks configuration variables that are
  initialized, and optionally prints them out as part of the
  prelude/header (based on --show-config), both in a dry-run (plan)
  and in an actual deployment (apply).

* It tidies up some of the colorization and messages, and includes
  nice banners like "Deploying changes:", etc.

* Fix an assertion.

* Issue a new error

      "One or more errors occurred while applying X's configuration"

  just to make it easier to distinguish configuration-specific
  failures from ordinary ones.

* Change config keys to tokens.Token, not tokens.ModuleMember,
  since it is legal for keys to represent class members (statics).
