Title: Custom and i18n error messages for invalid format dates

Previously, when a date was provided in an invalid format, there was no way to modify the error message that the validator raised.

Now it is possible to provide both custom error messages and override the defaults via i18n.

In this respect, it is now consistent with the rest of the Rails Active Model validators.
