What will we get: - console would be included into snapshot and allow us to reduce time that we spent in contextCreated function (~5 times faster), - it allows us to make further small improvement of console methods, e.g. we can implement super quick return from console.assert if first argument is true, - console calls are ~ 15% faster.
