* Error handling: introduced GPGMEJS_Error class that handles errors
at a more centralized and consistent position
* src/Connection.js:
The nativeMessaging port now opens per session instead of per
message. Some methods were added that reflect this change
- added methods disconnect() and reconnect()
- added connection status query
* src/gpgmejs.js
- stub for key deletion
- error handling
- high level API for changing connection status
* src/gpgmejs_openpgpjs.js
- added stubs for Key/Keyring handling according to current
state of discussion. It is still subject to change
* src/Helpers.js
- toKeyIdArray creates an array of KeyIds, now accepting
fingerprints, GPGMEJS_Key objects and openpgp Key objects.
* Key objects (src/Key.js) Querying information about a key
directly from gnupg. Currently a stub, only the Key.fingerprint is
functional.
* Keyring queries (src/Keyring.js): Listing and searching keys.
Currently a stub.
