Fixed finder string equal comparison to work with case-insensitive camelCase strings

finder string equal comparison doesn't work with case-insensitive camelCase
Bugfix for missing after_save call, when updating a model
More robust argument checking, plus README update.

The `Validatable::validate` class method now not only guards against the
`validation_type` argument being an empty hash, but also makes sure that
`validation_type` is in fact a hash as well. In either event, an
exception is raised and a useful error message is displayed. Updated
relevant spec.

The README now describes validation syntax correctly and a little more
explicitly.

Closes #106.
Further spec coverage for `Validatable::validate`.

Spec update to cover the case where no validation_type argument is
passed to the `Validatable::validate` method.
