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).

- Corrects an error with `--search`. Previously, `--search` was not
aware of whether it was outputted to a TTY, and would apply colorization
at all times. This resulted in unwanted behavior when, for example,
piping search results into a paginator.
- Corrects an error with `--color`. Previously, `--color` would be
ignored if output was being written to a non-TTY. This made it
impossible, for example, to `cheat tar --color | less -R`, as
colorization would always be stripped. The behavior of `--color` has
been modified such that it now behaves similarly to `--color=always` in
other applications.
