Title: `berks show` should not install cookbooks for the end user

`berks show` should delegate to a `Berksfile#show` function. This wouldn't run install for the user.

Instead it should check if the lockfile exists and show information based on that. If no lockfile is present then to let the user know they need to run `berks install` first.
