js: Treat a connection as a gpgme Context

--

* After an operation a connection should be disconnected again.
  The "end of operation" is now assumed to be either an error as
  answer, or a message not including a "more"

* GPGME, GPGME_Key, GPGME_Keyring don't require a connection
  anymore
* Message.js: The Message.post() method will open a connection as
  required
