vue 扩展时间指令 功能时间转换成文字例如：（刚刚、2分钟前、

/**
    * 使用方式:1、时间戳毫秒级 <div  v-z3-time="{ time: '1521279696000', type: '1' }"></div>
              2、日期格式<div  v-z3-time="{ time: '2018-03-22 10:21:12', type: '2' }"></div>
              3、type=1 & type=2
                     （1）新闻的资讯按照时间1小时以内的是“多少分钟前”，1分钟内的资讯显示“刚刚”表示
                     （2）当天内显示“小时:分钟”， 如“1:00”
