From composer.json: `"sentry/sentry": "^0.13"`
Latest 0.x `sentry/sentry`: 0.22.0
sentry/sentry 0.16.0 changed the function signature of Raven_Client::capture():
0.16.0: `public function capture($data, $stack = null, $vars = null)`
0.15.0: `public function capture($data, $stack, $vars = null)`
While the test suite silently passes with PHP < 7.1, running the test suite with
PHP 7.1 fails with the following error:
`Declaration of Monolog\Handler\MockRavenClient::capture($data, $stack, $vars = NULL)
should be compatible with Raven_Client::capture($data, $stack = NULL, $vars = NULL)`
This adds an internal release number to the raven handler. The release
number is added to what is sent to sentry unless something already is
present because a release number was sent via "context" or "extra".
tests/Monolog/Handler/RavenHandlerTest.php into a separate file so that
the test can pass when raven-php is installed and can be skipped when
raven-php is not installed. Addresses @Stof's comment in
