A gem for rails 2, 3 and 4 that retrofits and improves rails 4 functionality

Rails 4 offers 2 very useful dependent restrictions:
```ruby
dependent: :raise_with_exception
dependent: :raise_with_error
```

In rails 3 it was just:
```ruby
dependent: :raise # same sa raise_with_exception
```

In rails 2 these didn't exist, it was just
```ruby
dependent: destroy
```

Which is available in rails 2, 3 and 4

## Differences from standard rails 4

* Error includes detailed message which shows up to 5 of the records that are dependent
  This is useful for users to know which dependencies must be removed before they can
  remove the parent record
