* Cleanup of `lib/slackify` folder.
* Added a new configuration: unhandled_handler. You can specify a subclass of `Slackify::Handlers::Base` in the config. This class will be called with `#unhandled` when a message has no regex match.

 When sending an interactive message to a user, slack let's you define the `callback_id`. The app uses the callback id to select the proper handler for the message that was sent. The callback id must follow the given format: `class_name#method_name`. For instance if you set the callback id to `repeat_handler#repeat`, then `RepeatHandler#repeat` will be called. Adding new handlers does not require to update the `config/handlers.yml` configuration. You only need to update the callback id to define the proper handler to be used when you send an interactive message.

-The code also has an example of a slash command and its handler (`slash_handler.rb`). To add a command on the bot, head to you app configuration on https://api.slack.com/apps and navigate to Slack Commands using the sidebar. Create a new one.

The format is `/toddlerbot/slash/[handler_name]/[action_name]`. An app shouldn't have many slash commands. Keep in mind that adding a slash command means that the whole organization will see it.
