Added source location tracking to various packages.

* src/guile/skribilo/package/base.scm: Autoload `parameters'.
  (ref)[skribe-ref]: Use `search-path' and `*document-path*' instead of
  `find-file/path' and `skribe-path'.

  Initialize the `loc' field of markups.

* src/guile/skribilo/package/eq.scm: Likewise.

* src/guile/skribilo/package/pie.scm: Likewise.

* src/guile/skribilo/package/slide.scm: Likewise.
