Title: Entity#serializable_hash must also check if attribute is generated by a user supplied block

Tested the latest updates to master with my app and ran into this issue. One of my entities contains a *links* attribute generated by a block, like this:

``` ruby
expose :links do |model, options|
[
{ "whatever" => "/link?resource_id=#{model.id}" }
]
end

With #203 the :links attribute was not serialized.
