* Better recognition of just about everything.
 * Lots of bug fixes.
 * Make it easier to drop in user-provided handler definitions in the
   handlers/ directory.

** Added Class instrumented-module:
*** This class has a :default-component-type of
    instrumented-cl-source-file, and initargs :additional-dependencies
    and :override-dependencies, which control the dependencies of the
    components the module contains.
** Added initargs to instrumented-cl-source-file:
*** :translated-name replaces the :component-translations initarg of
    the component-file component.
*** :translated-pathname-form replaces the pathname part of the
    :component-translations in component-file.
*** :additional-dependencies and :override-dependencies as in
    instrumented-module.
** It is no longer possible to pass alist translations to the
   component-file component; instead, use instrumented-cl-source-file
   and instrumented-module components in the instrumented systems and
   pass the translations directly.
