基于Zhifeiya的分页控件改版的分页。
html显示代码：
<div class="pagelist">
{{.pagerHtml}}
</div>
controller调用代码：
currentPage, _ := this.GetInt("cp")//当前页
pageSize, _ := this.GetInt("si")//每页记录数
var po pager.PageOptions
po = pager.InitPager("/admin/menu/", pageSize, currentPage, "")
list, total := rmBll.QueryMenuListPager(nil, po.Start, po.PageSize)
po.Total = total
var pagerHtml string = pager.GetPagerInfo(po)
this.Data["list"] = list
this.Data["pagerHtml"] = template.HTML(pagerHtml)
分页代码：前台样式根据页面样式自行调整
