Title: Additional data access methods

Hello.

I have added two methods.

Audit#changed_by that returns a user object.
I did not like to call "user" because my project hasn't User model.

Auditing#last_change_of(attribute) that returns last change of attribute if it exists. This can be used if you audit few attributes, but not all of them changed every time.
This method not very efficient. But it still can be useful in cases when you not have very much changes on audited models.

Simple specs are also included.
