This changes the color usage to be determined dynamically. Prior to this the config was always read. That meant that if the scenario was ever written to disk (using save_configuration), it stored the value of colors_possible? and uses that indefinitely.
After this change, the value of colors will remain nil (determined at runtime) until the user uses --[no-]colors, which is then persisted.
