SAE版富文本编辑器umeditor
在sae上做了个小应用，需要用到富文本编辑器，自己就移植了一下ueditor的mini版umeditor，主要是改写了Uploader.class.php上传类，添加应用模式和上传域的参数设置，默认为普通模式common，在sae上设置为sae模式即可。
在imageUp.class.php下正确设置APP_MODE(默认common模式)，在实例化Uploader时正确设置storage的domain（默认uploads）即可，
/umeditor/php下的Uploader.class.php和imageUp.class.php

覆盖原文件即可，同时umeditor.config.js里面的图片修正地址也要设一下
