* Don't do runtime delegation, delegate explicitly
If someone accidentally calls `super` instead of `object` inside a decorator,
all hell breaks loose.
```rb
class Post < ActiveRecord::Base
def title
"title"
end
end
class PostDecorator < Draper::Decorator
delegate_all
def title
super and "overriden title"
end
end
post = PostDecorator.new(Post.new)
post.title #=> "overriden title"
post.title #=> "title"
```
This patch makes both `super` and `object` work. I'm not sure why
runtime delegation was added in the first place, but it seems very wrong
to add methods on the fly.
* Add documentation and more tests.
* Consistent line spacing in test.
