Now, you can optionally specify a ConsoleClient, to customise the behaviour of the LibJS Console. To customise the console, create a new ConsoleClient class that inherits from JS::ConsoleClient and override all the abstract methods. When Console::log() is called, if Console has a ConsoleClient, ConsoleClient::log() is called instead. These abstract methods are Value(void) functions: you can return a Value which will be returned by the JavaScript function which calls that method, in JavaScript.
