Title: More words added to the blacklist

An older fork already has these, but did not make a pull request:
https://github.com/ealdent/profanity_filter/commit/33d956b20d36541f8c0aea4838dcff2b67160707

I created my own fork as I may add a few other simple features like exposing custom blacklists and whitelists.
