Clarified the :wrap_object documentation.

It was not made clear enough that the callable needs
to return the object. Fixes #103.

```
Note that the `:wrap_object` expects an object that is _callable_, so any `Proc` will do. So you could as well use it to do some fancy extra initialisation (if needed).
But note you will have to return the (nested) object you want used.
E.g.
```
link_to_add_association('add something', @form_obj, :comments, :wrap_object => Proc.new {|comment| comment.name = current_user.name })
link_to_add_association('add something', @form_obj, :comments,
:wrap_object => Proc.new { |comment| comment.name = current_user.name; comment })
```
> A cleaner option would be to call a function that performs this initialisation and returns `self` at the end.
