In #2975 we introduced a way to opt-out of ANSI coloring by setting an environment variable (NO_COLOR).

This issue is about introducing two more alternative ways to opt-out of ANSI coloring:

1. Via a new command-line switch e.g. --no-color and/or --settings_color=never

2. Via a configuration setting in cake.config

For the configuration options, I suggest adding a new configuration value under Settings called Color, which can be one of the following values:

• auto - Let AnsiDetector decide if color is supported or not based on environment (default)
• never - opt out of coloring, regardless of environment (skip the logic to detect if color is supported or not)
• always - opt in on coloring, regardless of environment (skip the logic to detect if color is supported or not)

The color option would be available as ...

• An argument passed into Cake: --settings_color <value>
• A configuration file value: Color=value (under the Settings section)
• An environment variable: CAKE_SETTINGS_COLOR=value

... and follow the same priority order as other configuration values.
