Subject: One step further with the Guile port.

* src/guile/skribilo.scm:  Use `getopt-long'; include all the necessary
  modules that user-visible macros depend on.
  Use `read-hash-extend' to allow for DSSSL-style keywords, as needed by
  Skribe modules.

* src/guile/skribe/debug.scm:  Export `with-debug' and `%with-debug'.

* src/guile/skribe/lib.scm (new):  Fixed.
  (define-markup):  Fixed (more the `rest' argument to the end).
