添加CSS样式方案

如果把网页区分成内容和布局，那么“模板”就是内容，而皮肤就是“布局”
修改皮肤属性时，更新“主样式表”，前台就会随着改变

皮肤样式表(global.css)

<table class="listtable" cellspacing="0" cellpadding="0" border="0" style="width:100%;border-collapse:collapse;">
		<tr>
			<th scope="col" style="width:40px;">ID</th>
			<th scope="col" style="width:120px;">CSS样式方案名称</th>
			<th scope="col" width="*">CSS样式方案路径</th>
			<th scope="col" style="width:70px;">页宽</th>
			<th scope="col" style="width:70px;">左宽</th>
			<th scope="col" style="width:70px;">右宽</th>
			<th scope="col" style="width:70px;">操作</th>
		</tr>
		{#foreach $T.table as record}
		<tr onMouseOver="this.style.backgroundColor='F3F7FF'" onMouseOut="this.style.backgroundColor='FFFFFF'">
			<td align="center">{$T.record.id}</td>
			<td align="center">{$T.record.title}</td>
			<td align="left">{site.Dir}skins/{$T.record.source}/</td>
