    - *INCOMPATIBLE CHANGE*: the 'test_dirs' sub and '_build_test_dirs' method
      have been renamed to 'test_files' and '_build_test_files' respectively,
      and deal with arrayrefs rather than hashrefs, to more properly reflect
      the format of their values
    - add new 'WriteMakefile_arg', 'test_file', 'exe_file' options, to allow
      for simple use without needing to subclass this plugin
