Lots of changes, again.

Lots of changes, notably the following:

* skr/*.skr:  Moved engines to `src/guile/skribilo/engine'.

* src/guile/skribilo/engine.scm (lookup-engine):  Rewritten.  Don't use
  the auto-load alist.

* src/guile/skribilo/evaluator.scm:  New name of the `eval' module.
  `eval' couldn't be used as the module base-name because of Guile's
  recursive module name space.
