* Introduced Mocha/chai as testsuite. After development build
'npm test' should run the unit tests. Functionality exclusive to
Browsers/WebExtensions cannot be run this way, so some other testing
is still needed.
- package.json: Added required development packages
- .babelrc indirect configuration for mocha. ES6 transpiling
needs some babel configuration, but mocha has no setting for it.
- test/mocha.opts Vonfiguration for mocha runs
* Fixed errors:
- Helpers.js toKeyIdArray; isLongId is now exported
- Key.js Key constructor failed
- Message.js will not throw an Error during construction, a new
message is now created with createMessage, which can return an
Error or a GPGME_Message object
* Tests:
- test/Helpers: exports from Helpers.js, GPGME_Error handling
- test/Message: first init test with bad parameters
