Made a gem out of an earlier proof-of-concept: https://github.com/henrik/activemodel-with_conditions

This lets you do things like

``` ruby
with_conditions(if: :feature_x_is_on?) do
validate :free_plans_must_have_x, if: :free_plan?
end
```

where the conditions merge intuitively, unlike `with_options`.
