消息Message

微信有许多消息类型，例如 文字、语音、视频等等。

Message 是所有消息类的父类，也就是所有消息都含有以下的属性（之后每个消息类就不再讲解这些公共属性）。

Message的raw['MsgId']为一个很重要的属性，代表着一个消息的ID，之后也会比较常用，特别在资源消息类中尤为常见。

所有的Message中的message都是经过html_entity_decode()以及str_replace('<br/>', "\n", $content)的处理

所有的message子类都会保存在Hanson\Vbot\Collections\Message中，可以通过 message() 获取存储message的单例实例
