v0.5.0

git-nomad is no longer considered a prototype and is approaching its (hopefully final) 1.0 release.

Changed

• Update to the 2021 edition of Rust.
• Update to clap v3 for the command line interface.
• Help messages are no longer colorized, matching the lack of color throughout the rest of the implementation.
• Assorted minor version updates to various dependencies.

Fixed

• Adjust help message to only suggest -vv for max verbosity.
