short aliases for common options

[ssube]

Summary

Add short aliases for help and the other include options, to match -v for --version and -t for --include-tag.

Scope

• --help: -h
• --include-level: -l, --level
• --include-name: -n, --name

Use Case

The most common options should have single-letter aliases.

The --include-* options are the "default" way to filter rules (exclusion is more complicated and less useful), and --include-tag is already aliased to --tag and -t.
