monitor: Add option to force output color
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).
