Outside the context of a rails / merb app, the Delayed::Worker.logger can be nil.
It'd be nice to have a default logger, or at least pick up the rack logger if it's in use
I can create a patch for this, if there's interest.
Ah, insert foot in mouth, there's a 'say' method that will output unless quiet is set.
Don't use rails_env in capistrano if it's not set. closes #22
