Overhaul: emphasized logical separation of the modules.

* src/guile/skribilo/types.scm: Removed.  Moved the class and method
  definitions in the relevant files.

* src/guile/skribilo/ast.scm: New.

* src/guile/skribilo/location.scm: New.

* src/guile/skribilo/parameters.scm: Same as part of the former
  `vars.scm' except that it uses fluids instead of globals.

* src/guile/skribilo/vars.scm: Renamed to `compat.scm'.

* doc/Makefile: Removed (generated by `configure').
