* bin: Removed.

* skr: Removed (files moved to `src/guile/skribilo/packages').

* skribe: Removed.

* doc/skr/env.skr (*courtes-mail*): New.

* doc/user/user.skb: Removed postal addresses, added my name.

* src/guile/skribilo/engine/lout.scm: Uncommented the slide-related
  markup writers.

* src/guile/skribilo/evaluator.scm (%evaluate): Try weird things with
  source properties.

* src/guile/skribilo/reader/skribe.scm: Comply with the new guile-reader
  API.

* src/guile/skribilo/types.scm: Removed the special `initialize' method
  for ASTs which was supposed to set their location.
