Replace docopt-go with spf13/cobra, giving cheat a built-in `--completion` flag that dynamically generates shell completions for bash, zsh, fish, and powershell. This replaces the manually-maintained static completion scripts and resolves the root cause of multiple completion issues (#768, #705, #633, #632, #476).
