Fixes#306 adding command line autocompletion. These are generated to: CARGO_TARGET_DIR/item-hash/out/. These will need to be packaged for distros later, it's unclear how we could use cargo install with these as cargo doesn't support arbitrary artefacts like this (yet?).
Fixes#13 and Fixes#135 - webauthn and webauthn with cli. This is the core of webauthn, but only as a single factor. Some changes are still needed for webauthn as MFA and as a verified single factor. This will be made in a subsequent PR.
Implements #132, the recycle bin. This completes the feature, with working API's, front end tests and CLI tooling. It also includes a refactor of the CLI tools to make them a bit easier to manage/work with.
