Sometimes we want to force output color even when stdout is not a terminal, for example when piping the output to a filter script and then piping it further to a pager which can display colors. This patch provides a general option to force whether color is on or off (always and never), or leave btmon to decide (auto). Reviewed-by: Daniel Winkler <danielwinkler@google.com>
