Use multi_json for rendering

Config option overload.

Describe the feature you'd like to see implemented

multi_json is a popular gem (that we'd need to depend on) for automatically choosing the fastest JSON renderer your application or library has available:

MultiJson.dump({:abc => 'def'})

I've used other serializers, like grape-entity, that support it, as well as many applications. This would simplify configuration by moving it up a layer outside of our library. We could still offer an override for rare cases if we want, maybe via an extension hook.

IMO, the library shouldn't have a favourite. Extensions should be the way to go ahead for people wanting that extra performance. For majority of the users, the native JSON lib should suffice.

This is now implemented in #479 with the option to override via an extension hook.

Edit:

If we dislike the idea of adding a dependency, we could change the above so that the multi_json behavior is available as a built-in, optional V2 extension. That way the application is responsible for handling that dependency.

class ApplicationBlueprint < Blueprinter::V2::Base
  extensions << Blueprinter::Extensions::MultiJson.new
end
