can you add WeChat user-agent?

[Relsoul]

I often use device.js, but most people in China use WeChat. so can you add WeChat to device.js? thanks!

this is weChat user-agent

function is_weixin(){
	var ua = navigator.userAgent.toLowerCase();
	if(ua.match(/MicroMessenger/i)=="micromessenger") {
		return true;
 	} else {
		return false;
	}
}
