js: getDefaultKey and GenerateKey improvements

--

* src/Keyring.js: added more options for key generation.

* src/Key.js: GetDefaultKey now relies on the info associated with the
  key, as the approach of relying on a secret subkey did not work as
  intended
* DemoExtension: Added a button for retrieval of the subkey, to test
  this functionality.
