Use load() instead of require

To get rid of old code, you might want to do something like I do.

inside a particular 'module':

class Foo < ScriptModule
  def initialize() ...
    register_command("foo") { |args| ... }
  end
  def cleanup
    unregister_command("foo")
  end
end

When I load() a script module, I attach all its class to its filename.
When I want to reload said filename, I first call cleanup, causing it to
unregister old code, etc, and then load() it again.
