* Connection.js
- Add some meaningful nativeMessaging feedback for failing
communication due to misconfiguration or other browser-originated
fails
- add an "isDisconnected" property
- "isNativeHostUnknown" tries to match browser's feedback string if
the browser does not find gpgme-json
* init.js
- initialization will now reject with a more meaningful error if the
configuration is not set up or other browser-based errors
(chrome.runtime.lastError) are present. This should speed up
the normal initialization (not having to waiting for a timeout
any more in case of improper setup)
* errors.js
- CONN_NATIVEMESSAGE: New error that passes the browser's
nativeMessaging error
- CONN_NO_CONFIG: native messaging error indicating that the
nativeMessaging host was not set up properly
* unittests.js:
- added the "isDisconnected" property to the startup tests
- added tests for proper behavior of connection checks
