修改 Latestnews模块，改进显示效果
根据 http://forum.mamboserver.com/archive/index.php/t-53156.html和 Latestnews modified模块修改而成，可以使条目的颜色交替显示，显示文章的创建时间，显示“更多”链接（链接到catagory），指定itemid来使用 menu 对应的模板。
首先修改的是xml文件，增加了几个变量： 引用:<?xml version="1.0" encoding="iso-8859-1"?>
<mosinstall type="module" version="4.5.2">
<name>Latest News MODIFIED</name>

<description>显示最新文章模块，显示文章的创建时间，可以设置颜色交替显示，可以根据菜单设置模板</description>

</table> 为了使条目可以交替颜色显示，在模板的 CSS 文件中增加： 引用:.sectiontableentry1 {
background-color : #254F25;
color:#FFFFFF;
}
.sectiontableentry2 {
background-color : #003300;
color:#FFFFFF;
font-size:10px;
