Improving the auth.js middleware

[ugz-man]

The auth.js middleware is too simple I can improve it by adding stuffs like:

• Check if the user still exists
• Checking if the user recently changed password after the token was issued
• Add the already logged in user on request object for easy access down the middleware pipeline

I will have to modify the auth.js middleware file and User model and maybe some other files

Please assign this task to me.
