Title: Remove hardcoded references to id and created_at fields

The gem assumes the generated migration is run without modification and refers to id and created_at fields throughout.

The first two commits change the version model to use the class' primary key instead of referencing id directly.

The last commit adds a configuration option for "timestamp_field" which allows the user to specify the name of the field which is used to track when the version was created.
