KindEditor的上传图片CGI(JSP版)

见过、用过很多网页在线编辑器，如：fckEditor、eWebEditor、htmlarea等，也简单看过、修改过其中的代码。但我觉得KindEditor的框架结构最为小巧、合理、精致。程序代码比较优美、易懂。

　　功能上，有个我也比欣赏的，就可提供了方便的上传本地图片的扩展编程接口，自带了asp、php的上传CGI程序。我做的项目里一般用java用的比较多一点。可官方没有提供，就自已写了一个。相信有跟我一样需求的朋友，把程序贴在下面，大家拿去用好了。

　　我还添加了一个上传附件的功能，跟上传本地图片编程方法基本一致，就不过多介绍了。

注：此代码在2.4KindEditor版本中测试通过。目前的最新版本为：3.1.1，其js代码变化比较大，不知还能不能用，我没有进行测试。
