js: Configuration and Error handling

--

* gpgmejs_openpgpjs
  - unsuported values with no negative consequences can now reject,
    warn or be ignored, according to config.unconsidered_params
  - cleanup of unsupported/supported parameters and TODOS

* A src/index.js init() now accepts a configuration object

* Errors will now be derived from Error, offering more info and a
  stacktrace.

* Fixed Connection.post() timeout triggering on wrong cases

* Added comments in permittedOperations.js, which gpgme interactions
  are still unimplemented and should be added next
