IRC tags with a value of 0 or 1 are ALWAYS converted to a boolean

	// Transform IRCv3 tags..
	if(message.tags) {
	var tags = message.tags;
	for(var key in tags) {
	if(key !== "emote-sets" && key !== "ban-duration" && key !== "bits") {
	var value = tags[key];
	if(_.isBoolean(value)) { value = null; }
	else if(value === "1") { value = true; }
	else if(value === "0") { value = false; }
	else if(_.isString(value)) { value = _.unescapeIRC(value); }
	tags[key] = value;
	}
	}
	}

In some cases the original tag value is an actual integer, not a boolean. For example a resubscribe for 1 cumulative months. This is returned as a true value, which is surprising.
