Maximilian Krambach e16a87e839 js: Making objects inmutable
--

* An Object.freeze should stop any malicious third party from changing
  objects' methods once the objects are instantiated (see unittest for
  an approach that would have worked before)
  - An initialized gpgmejs- object doesn't have a '_Keyring' property
    anymore (it still has its 'Keyring')
  - The internal expect='base64' needed to be turned into a method.
