Don't Require Ruby to Build

[defuse]

Check wordlist.h into the repository so that you don't need ruby to build it.

[defuse]

Oh wait, it's already in there, but it's failing for someone who doesn't have ruby:

ruby tools/generate_wordlist.rb libs/wordlist.txt > libs/wordlist.h
/bin/sh: 1: ruby: not found
make: *** [libs/wordlist.h] Error 127

[defuse]

So we need to tell make to do something like "generate wordlist.h only if it isn't there" or something like that.

This was more or less fixed with this, wasn't it? 6885bc9
