Give -v to verbose, move --version to -V (closes #64)

urfave/cli's built-in version flag claimed -v by default, colliding with
the -v verbose alias used on every subcommand; "mfer -v --version" failed
to parse with an internal-sounding parser error. Verbose is the more
common meaning of -v in tools that offer both, so verbose now keeps -v at
the root and on every subcommand, and the version flag takes the capital
-V (--version still works).

User-visible change: -v alone now prints help with verbose logging rather
than the version; use -V or --version for the version.

The --version flag and the version subcommand now share one printer, so
they emit identical output. Adds tests covering -v, --verbose, --version,
-v --version, and --verbose --version (exit code and output).
