Set Language Validation

[devinmatte]

Right now there's the function for adding a language:

def lang(self):
    # TODO: Default
    # TODO: Validation
    self.details['lang'] = input("Language " + str(on(["M"], args)) + ": ")

I need to check it against the available languages to pick from to make sure that users can't put in invalid options.

@devinmatte I would like to work on this, I've never contributed to any Open Source Project.

Here is what I understood -
The user will input a language which needs to be checked against these available languages.

Here are my doubts -

1. In what form user will input text - in complete form (like "English/english") or in code form (like "en")?
2. If the user enters wrong input, what response should be given?

@saifat29 I'd love for you to work on this!

So yes I need to check against the available languages.

1. Use the codes en would be valid while english would not
2. Look at privacy for an example of what to do with invalid input

Thank you, all my doubts are solved. I'll do a Pull Request when I'm finished.
