Title: Require the dependencies necessary for Fetch and Actor in their respective files.

Ran into an issue implementing DynamicFetch similar to this: https://zeropush.com/blog/dynamic-queues-in-sidekiq

The trouble was that requiring sidekiq/fetch for extension led to some missing definition errors. This code fixes the issue.

One possible tweak is to only require celluloid when Actor is included.
