Automate the setup process for new users

[Shankhanil]

For new users wanting to use the bot, setting up the bot might be a bit intimidating. This issue deals with automating the setup process for new users, with interactive walkthrough

So, here's an interesting approach; the bot should prompt the user to enter their own details inside of the bot, if they haven't provided any credentials. This would make the bot very easy to use-- just run python3 bot.py and paste what it asks from you! The bot will then have to write the values inside of a configuration file.

If there's any exception when logging in, the bot should handle that by removing the credentials and asking for them again. This should only happen if the user hasn't provided any environment variables or if they haven't entered anything in the configuration file-- in either case, the login should proceed as normal.

I'll add labels to this issue in order to attract people to it as soon as #13 gets merged, because the configuration system is currently being worked on.

This is exactly the approach that I was thinking about. I am working on this approach now. I will make necessary changes when #13 gets merged.

Good. Make sure to introduce an environment variable that skips this, in case the bot is either in a continuous environment or in a Heroku instance.

Let me know if there's a test to check that. @AlwaysLivid
