crecord: honor "ui.color = no" config option

The current implementation of crecord ignores the ui.color setting.
This patch checks the ui.color config option and does the curses setup
without colors when the option is set to a falsy value. For other (or
missing) setting of ui.color, curses setup is done as before and uses
colors.
