Synchronize with miso-belica/readability.py fork

Hi,
I did some cleanups here and there to be able to merge our work together automatically. I think it would be waste of our time to work separately. Please check the changes and merge them. 

I would appreciate if you grant me push access to the breadability repository so I could work directly in the repo. But if you don't I understand it and I send pull request with my changes. I don't plan to work much on readability in the near future, but I would like to push some fixes, README updates, ... directly.

Anayway thanks for your work :)
