- Implement the 'upload' feature to the freedb servers. Actually,
  I have the core developed on the get_from_user() function, but I 
  still couldn't find enough time to rewrite some of the function
  body and test it exhaustivally.

- Add an option to allow the user to select which of the entries
  he/she wants to use, in case of more than one incident of the
  cd_id in the freedb server.
