Optional 2FA code on first login

[Noobgam]

This is kinda useful, especially when your bot is well-established, .auth files are there, bot always fails his first login attempt without this, if you spam this (e.g. restart bot or something), steam is going to temp-ban you for incorrect login attempts.

So far it worked fine for me, bot is able to login on his first attempt and I don't know when is it reasonable to login without 2FA when .auth files already exist

Perhaps adding it as an option to the configuration file is even better

Just wanted to add to this. Maybe in the constructor have it check for a .mafile that matches the username and sets "useTwoFactorByDefault" to true? That way we should be able to skip having to set it to true when creating a new bot.
