This adds a swarm ls command which lists files and directories stored in a manifest. Rather than listing all files, it uses "directory prefixes" in case there are a lot of files in a manifest but you just want to traverse it. This also includes some refactoring to the tests and the introduction of a swarm/api/client package to make things easier to test.
