Merge: console: don't color output when stdout is not a TTY (by default)

Change the behavior of the `console` package to ignore color commands like `Text::green` when stdout is not a TTY. You can override this behavior by setting `force_console_colors = true`.

I made this change to color the output of nitpm, however, it can be useful to other tools to support stdout redirection by default.
