Previously, users cannot enable boolean flags like `--show-all` in bat's config since all options were expected to be either a string, or a list of strings. With this commit boolean flags are simply appended to the end of the config if they are set to `true`, and discarded otherwise. For example, the config { theme = "TwoDark"; show-all = true; lessopen = false; } would produce a config file that looks like --theme='TwoDark' --show-all Fixes #4657
