[IMP] Connect GitHub Login Flow

[thealphadollar]

This is a high priority, good learning opportunity task (which anyone can take up just like anyother task).

We have already made some frontend (#20 ) and backend (#8 ) but it is not connected at the moment. We should connect it and following should be the approximate flow of the button;

• User clicks it and is redirected to github OAuth login
• Once he verifies, we should get a token
• Token is returned to a backend service which then fetches the required information about the user
• This token should get stored along with User's data in the sheet so that in future also we can use it.

@xypnox Please add the details of what we need to get from the github regarding the user at the time when he signs up for KWoC.

Ping @xypnox Could you provide the details that needs to be fetched from the github account of the user? EDIT : The User data we are planning to store - UserID Avatar Url College Name
