Each module is an object inheriting from Resmon::Module as before, but the
code to support coderefs and raw packages with a handler function is all gone.
In addition, a lot of redundant code was removed, and some small changes made
to the modules themselves:

    - The check name is stored in $self->{check_name} (instead of
      $self->{object} as in the past)
    - The check configuration is stored in $self->{config} and not just as
      instance variables.
    - All modules must have fully qualified names in the config file. In other
      words - Resmon::Module::Resmon instead of just RESMON. In keeping with
      other perl module names, I've gone with Title Case instead of ALL CAPS
      for the sample module (Resmon). This is simple to change back if desired
      however.
