js: encrypt improvement and decrypt method

* Compatibility class gpgme_openpgpjs offers an API that should accept
  openpgpjs syntax, throwing errors if a parameter is unexpected/not
  implemented
* tried to be more generic in methods
* waiting for multiple answers if 'more' is in the answer
* more consistency checking on sending and receiving
* updated the example extension
