Safe v0.0.10

New Features

• safe now writes a small ~/.svtoken file for other
  applications (like [Spruce][1]) to use without having to
  understand the ~/.saferc file format.
• safe now understands the vault subcommand, allowing users to
  hook up targets in ~/.saferc to the vault cli.

Bug Fixes

• safe no longer requires the ~/.vault-token file to be set.
• safe now correctly uses the tokens listed in ~/.saferc when
  connecting to the targeted vault.
