Towards a self-hosted user manual.

* doc/skr/api.skr: Use `(skribilo reader)' and `(skribilo utils syntax)'.
  (api-search-definition): Added a SKRIBE-SOURCE? argument.
  Determine the appropriate reader based on its value.
  (keyword->symbol): Removed.
  (define-markup?): Fixed.
  (make-engine?): Fixed (but unverified).
  (make-engine-custom): Likewise.
  (sym/kw?): New.
  (define-markup-formals): Fixed.
  (define-markup-options): Likewise.
  (define-markup-rest): Likewise.
  (doc-markup): Added a SKRIBE-SOURCE? argument.
  (doc-engine): Likewise.

* doc/user/*.skb: Updated the `:source' arguments to `doc-markup' and
  `doc-engine'.

* src/guile/skribilo/utils/compat.scm (hashtable-update!): Fixed
  according to the Bigloo manual.
