5.4.0 - April fools

BC breaks

• Enabled session scoped bindings even when no session exists. However, retrieving a session scoped instance without setting a session will throw a \RuntimeException
• deprecated stubbles\ioc\Binder::setSessionScope(), use built-in session scope with session interface instead, will be removed with 6.0.0
• added stubbles\ioc\binding\Session as simple session interface for the built-in session scope
• added stubbles\ioc\Injector::setSession() to provide session instance for session binding scope, will also bind session interface to this instance so it is available for injection

Other changes

• added stubbles\streams\StandardInputStream
• added stubbles\streams\StandardOutputStream
• annotated stubbles\lang\errorhandler\ExceptionLogger with @Singleton
• added stubbles\lang\castToArray()
• stubbles\lang\Sequence::append() now accepts anything
