Replaced my homebrew keyword generator

It now uses the one found here: https://github.com/Donatello-za/rake-php-plus
This is much better than the one I had hacked together.

Makes AntCMS a bit bigger.. but not by too much. I may end up removing the keyword generator outright, but for now I'm going to keep it.
