Piping `history list` to `less` is hard to read -- disable ANSI colors when `process.stdout.isTTY` is not `true`

[Cafe137]

I have a long upload history, so I piped it to less to navigate it better. However, the output was hard to read due to the ANSI escape codes.

Most CLI apps only enable colors when stdout is a TTY, and disable them when stdout is not a TTY.

Please apply this fix to the history list command so that it doesn't use colors when piped to another command.
