The recent change to cast bool config vars as ints to handle a '0' or '1' value was shortsighted, since it doesn't allow for instances where the variable is set to an empty value (or '' or any invalid/non-int value). This introduces a read_config_bool method for reading values that should be a '0' or '1', but will default to False if not a digit (otherwise the value will be cast as bool(int(value)) if "value" is a digit str). Fixes #288
