Added the `~' markup. Added SRFI-62 and SRFI-30 support to the Skribe reader.

* NEWS: Added actual news.

* src/guile/skribilo/skribe/api.scm (~): New markup.

* src/guile/skribilo/engine/html.scm: Added a writer for `~'.

* src/guile/skribilo/engine/latex.scm: Likewise.

* src/guile/skribilo/engine/lout.scm: Likewise.

* src/guile/skribilo/evaluator.scm (skribe-include): Added a `:reader'
  argument.

* src/guile/skribilo/reader/skribe.scm (*skribe-reader*): Renamed to
  `%skribe-reader'.
  (%make-skribe-reader): Moved the sharp reader code to...
  (&sharp-reader): ... here.  Added support for SRFI-62 and SRFI-30
  (Bigloo supports both).
