Move websites.yaml into python classes

[seeeturtle]

Even they are attributes of a same website, They are separated from each other. I think we should make top level class that describes attributes for website, and make subclasses for each website.

What do you think about this?

No. It is data. Re-usable across language, and in different domains.

If you want, generate python classes from the data.
