Added reusable reloading support through the inclusion of the Relodable module that all subclasses of ActiveRecord::Base, ActiveRecord::Observer, ActiveController::Base, and ActionMailer::Base automatically gets [DHH]. Added auto-loading support for classes in modules, so Conductor::Migration will look for conductor/migration.rb and Conductor::Database::Settings will look for conductor/database/settings.rb [Nicholas Seckar]. Refactored extensions to module, class, and object in active support [DHH]
