Subject: [PATCH 1/2] fix: Template::render() accepts object for template
 parameters (#351)

Latte\Engine::render() supports passing an object as template parameters,
but Nette\Bridges\ApplicationLatte\Template::render() only accepted arrays.
This adds object|array union type to render() and renderToString().
