js: separate gpgme answer by type of data

--

* src/Connection.js; src/permittedOperations.js: To avoid further
  encoding problems, data sent by gpgme is now sorted  as either
  'payload' or 'info'. Payload data may come in any encoding, and here
  the 'expected' and 'format' options are used, 'info' data may
  contain text created by gnupg which may need re-encoding, but this
  should not be affected by 'expected' and 'format'
