Проверка, чтобы пользователь разрешил использование веб камеры или микрофона в Web Player'е.
This is used to check the result of a previous call to Application.RequestUserAuthorization. Explicit user consent to use features is only needed in the Web Player. In other build targets, this function will always return true.
Note: The web player is not supported from 5.4.0 onwards.
