Move the presentation part of the 'look' command out to the new scripting system. You can now make different scripted objects appear vastly different by overriding basicobject's return_appearance (or any of its submethods). Also fixed word wrapping, and we are now wrapping descriptions to 78 characters by default. We'll see how gracefully it handles this, and we might eventually apply it to all output.
