*HTML图文类，用于显示html内容
*
*支持的标签如下:
*a:链接标签，点击后会派发"link"事件 比如:<a href='alink'>a</a>
*div:div容器标签，比如:<div>abc</div>
*span:行内元素标签，比如:<span style='color:#ff0000'>abc</span>
*p:行元素标签，p标签会自动换行，div不会，比如:<p>abc</p>
*img:图片标签，比如:<img src='res/boy.png'></img>
*br:换行标签，比如:<div>abc<br/>def</div>
*style:样式标签，比如:<div style='width:130px;height:50px;color:#ff0000'>abc</div>
*link:外链样式标签，可以加载一个css文件来当style使用，比如:<link type='text/css' href='html/test.css'/>
*
*style支持的属性如下:
*italic:true|false;是否是斜体
*bold:true|false;是否是粗体
*letter-spacing:10px;字间距
*font-family:宋体;字体
*font-size:20px;字体大小
*font-weight:bold:none;字体是否是粗体，功能同bold
*color:#ff0000;字体颜色
*stroke:2px;字体描边宽度
*strokeColor:#ff0000;字体描边颜色
*padding:10px 10px 20px 20px;边缘的距离
*vertical-align:top|bottom|middle;垂直对齐方式
*align:left|right|center;水平对齐方式
*line-height:20px;行高
*background-color:#ff0000;背景颜色
*border-color:#ff0000;边框颜色
*width:100px;对象宽度
*height:100px;对象高度
*
*示例用法：
*var div:HTMLDivElement=new HTMLDivElement();
*div.innerHTML="<link type='text/css' href='html/test.css'/><a href='alink'>a</a><div style='width:130px;height:50px;color:#ff0000'>div</div><br/><span style='font-weight:bold;color:#ffffff;font-size:30px;stroke:2px;italic:true;'>span</span><span style='letter-spacing:5px'>span2</span><p>p</p><img src='res/boy.png'></img>";
