Refactor Box object in config.py to Machine model in database

[eshaan7]

Currently, the machine details are stored in a JSON object (box) in config.py file.

What's required:
Need to shift this into a Machine model in the SQL database (via SQLAlchemy model)
This will also enable support for multiple machines as described in issue #17.
Afterwards, we can create a rating system as described in issue #14.

Hi! Can I work on this?

Do remember that: You will need to make changes everywhere in the code and the templates, create_db.py as well. Also, would need to change the Score model to accommodate the new Machine model. In the Score model, we will need to add a foreign key to the machine ID.

Also, in the Machine model, please have these necessary fields:
id:int, name:string, user_hash:string, root_hash:string, user_points:int, root_points:int, os:string, ip_addr:string

PS - If you are able to do this, then #17 should be quite easy. So it's a two for one deal. :)

Thanks for the explanation. I'll get back to you if I have any queries.
