Unfollow only "botted" people

[simonuvarov]

The main point is that now you can unfollow people you have followed earlier so that people you want to read stay in your followings. Also I extracted some standalone functions "as mute_by_id" and "follow_by_id". Fixed logical problems with gaining "not-to-follow" list.

Yes, in one of the commits I forgot to delete my tokens, but I regenerated them so everything is fine.

why'd you close this?

I didn't think this pull request was going to be approved and I have changed a lot of code already and I think it'd be better to have two different repos.
Just check out my repo because I did some improvements like delays, private functions for saving each operation (I mean follow/unfollow ops.), reading tokens from file (in json, I think it's much better to use files instead of constants) and I renamed functions because the names were too long to me (that's why I thought my pull request was not going to pass). I mean using 'auto_' makes the names too complicated and there were other inaccuracies in naming variables.
