Tests will now run with one instance of gpgmejs each block,
which reduces overhead. Readability is (hopefully) improved),
some negative tests are added.
There is still a performance problem in base64 encoding/decoding,
which causes some tests to fail due to time out.

* trying to stick to eslint from now on for readability
* As some attribution was lost in previous git confusions, I added my
name into some of the licence headers
--
* After an operation a connection should be disconnected again.
The "end of operation" is now assumed to be either an error as
answer, or a message not including a "more"
* GPGME, GPGME_Key, GPGME_Keyring don't require a connection
anymore
* Message.js: The Message.post() method will open a connection as
required
--
* src/Connection.js: isConnected was renamed to checkConnection, that
returns a promise with either version information or Boolean
* Connection checks have been adapted to reflect that checkConnection
returns a Promise
* BrowsertestExtension: tests/signTest.js was missing from my last
commit
