wikipedia wordlist

[RABijl]

Hi, I've been using your project here and there and used a wordlist from wikipedia found in this repo. My question is if you would be interested in a pr where i add it to your project. What i'm thinking of doing is this:

1. Add a txt file with words from wikipedia.
2. Add an option to pass the txt file name as a parameter that defaults to words.txt.
3. Update readme with instructions on how to use the wikipedia wordlist.
