Refactor of prompts and the displayhook....
Refactor of prompts and the displayhook. * Renamed CachedOutput to displayhook.DisplayHook. * Added methods that DisplayHook.__call__ uses to do its work. These methods can now be overridden for the ZMQ kernel. * Removed all hooks (result_display and generate_output_prompt) that the outputcache was using. We need to add these back in once we figure out what to do about hooks in general.
