+ The configuration window now display the system section (still empty,
  but will contain the Mednafen path, shortcuts, etc) and a section for
  every plugin loaded. The plugin options supported will be: Integer,
  BiInteger (like resolution control), Real, BiReal (like scaling
  factors for the resolution), Enum (a list of fixed options), Boolean
  (Yes/no values). Still to add a path option (for files needed, like
  BIOS files).

! The system still hasn't plugins. So, at this moment, the system
  depends on the plugins foun in the paths configured.

! At this momento there are three sections of configuration options
  supported: Audio, Video and Controls options. Once I work on the
  NES plugin (by far the largest) I'll check if there is needed to
  add more sections.
