Lout engine: Implemented `slide-embed'.

* src/guile/skribilo/engine/lout.scm (lout-definitions): Renamed
  `@SkribeMark' to `@SkribiloMark'.  Added `@SkribiloEmbed'.

* src/guile/skribilo/package/slide/lout.scm: No longer use
  `define-skribe-module'.
  (slide-embed): Use `@SkribiloEmbed' (works fine).
