Title: Related to Issue #200, slight code clean-up.

This is a trivial pull request, it (naturally) still passes all tests, but is intended to allow me to more easily extend the SlugGenerator class, and borrow the behaviour which helps me writing my own implementation (`#wildcard`, `#column`, `#separator`, etc) whilst extending the parts which might need to be modified.

I'm planning to take the short route, to implementing my own Redis backed option, and would like to see this come upstream so that I might determine the best places to hook/override behaviour.
