1.6.0

Changed

• The [package.metadata] section for adding extra dependency information
  should now be named [package.metadata.aur]. The old syntax will still work,
  but you will be warned. This fixes a conflict with other cargo subcommands.
• The PKGBUILD and tarball are now output to target/cargo-aur to avoid
  cluttering the top-level of the repo.
• Reduced binary size.

Fixed

• LICENSE file checking is now done via SPDX identifiers.
