forbidden_keys feature

[asok]

Hi,
thanks for this gem, it made our work easier.

One thing though - in the readme you are mentioning that it is possible to forbid some words from being generate as a unique key. Yet the code does not use this array. Or am I missing something?

I've found commit that does add the feature c788542
But I cannot find a commit that removes the usage of forbidden_keys in the code that generates the unique key.

You're right, it seems along the way we dropped this feature. AFAIK this was not a conscious decision to remove this, and I suspect it was an unintended side effect of some refactoring. I am guessing that we didn't have a spec exercising this behaviour and someone neatened up the code without realizing the impact (similarly it slipped past reveiw). I will look at adding it back in, or alternatively if you would like this feature in a rush a PR would be most welcome.
