Checking if the constant is define and including the extensions directly
in the base class will for the class to be loaded. This may cause these
components to be loaded before the time and be missconfigured if the
sidekiq railtie is loaded before the components railtie.
It is unlikely to happen but is better be safe.
Replaced with `__send__` from std lib
* `send` can now be overridden to be more semantically meaningful
* `message.send(user_id)` as opposed to `message.send_message(user_id)`
* `__send__` makes it clear that the reflective version is intended
Workers are the user's classes, the threads are now called processors. Add secret sauce to make Rails config much easier. Use a railtie to auto-add app/workers to the autoload path.
