Generalize to ActiveModel so it can be used with other ORMs

This is the best slug library I've come across, but why tie it to ActiveRecord? Lately I've been starting all new projects on Mongoid. Should be easy enough to change, no?

if you want to come up with an implementation that is ORM-agnostic i'd definitely use. prolly. nothing against mongoid or any other orm, it's just that i use AR so the code i write tends to use it. totally open to other ways if you want to knock something up i'll take a look.

closing for now since no reply. open to this in the future though but as i only use AR... not gonna knock up implementations of stuff i don't use. YAGNI etc.
