Option to disable showBanner()

[alies-dev]

First of all, I would like to thank you for the amazing package -- it saved a lot of my time!

Today I found in source code an external call: fwrite(STDERR, Httpie::get("https://deployer.medv.io/banners/" . $this->getName() . $withColors)->send());. I really respect your work and understand why you added it. But on other hand - this is call of external service with all privacy/security concerns. I think is it possible to disable it, e.g. by using DO_NOT_TRACK flag or similar new flag?

Hi, I think something like DEPLOYER_BANNER env variable can be added, sure.
