Bumped to 1.0.0

[deprecation] The `refine` helper no longer exist, as it's a proposed keyword for ruby 2.0 look to the new features for how to access arcane.

[feature] Introducing chained methods on `params` to specify for what, who and how you want arcane to refine your parameters. Look in `README.md` for detailed information.

[bugfix] You can now properly specify `refinery_class` in your model.
