    js: Add key creation to Keyring
    
    --
    
    * src/Keyring.js: Added method generateKey for new Keys
      Still TODO: Key length and some further testing. Automated testing
      does not work in this case, and gpgmejs will not be able to delete
      test keys again.
    * src/permittedOperations.js Added new method's definitions according
      to gpgme-json
