Rake task for adding new languages

[divyanshumehta]

For adding new languages to the judge currently the code in submission _worker need to be modified which is not favourable thing. Rake tasks can be made for addition of new coding languages. This will aloow the admin to easy add languages to the Judge.

The idea is good, but for that, you have to modify not only submission_worker also submission model at create_submission_data

and If you want admin to add any new language then also add execution command field in languages model and modify accordingly. But the problem arises when you use docker containers or the language is not installed on the system. I am assigning this to u. Try to fix.
