Safe v0.4.3

New Features

• New safe ls command lets you list individual levels of the
  directory hierarchy. Could be useful for some shell
  auto-completion. Just sayin'

Improvements

• Fix a formatting issue with the output of safe x509 show
  where ANSI color code formatting was not properly applied.
• Targets with trailing slash(es) are stripped before being
  used, to avoid spurious 404's on write operations.
