[dmcnally]

Removed the patch to ActiveRecord::Validations::UniquenessValidator as it caused breaking changes.

See ticket #276

Test updated to reflect old behaviour

@radar any ideas on when this might be merged? Or feedback on any other changes that are needed?

If it's affecting you now then you can run on a fork of paranoia until it gets merged. I will merge it when I merge it.

I am not paid to work on open source at all. Emails like this just increase the guilt I feel when I try to relax on the weekends. Emails like this make me want to not maintain paranoia at all.

Actually, I'm done.

Sigh, if you're sick of open source just don't blow up on some guys' PR. It looks like you haven't really considered the cost of working on open source when you started. It happens to us all, just don't take it personally.

This is not so simple, and is a bit of a pickle.

Though 2.1.4 had a breaking change for 2.1.3 users it should not have had for a minor version, reverting it would be a be a breaking change for current 2.1.4 and 2.1.5 users. To achieve compatibility with both we'll have to add some sort of configuration.
