sheesy-cli 1.0.1

The 'share-secrets-safely' CLI to interact with GPG/pass-like vaults.
## V1.0.1: The very first release - with a new name!

`s3` now officially is `sy` on the command-line, and spelled `sheesy`. Crates
were renamed accordingly, too.

## V1.0.0: The very first release!

This is the first usable version, providing only the minimal amount of features.
A lot of the value contained is a fully automated system for quality assurance
and deployment, which will help keeping the releases coming.
