JTBC5.0实现编辑器粘贴图片自动上传

支持自动上传的图片：

1.电脑图片复制后(单张，多张)，在编辑器粘贴

2.截图软件截图后，在编辑器粘贴

3.聊天软件中图片复制后(单张)，在编辑器粘贴

4.办公软件中图片复制后(单张) ，在编辑器粘贴

不支持办公软件多张图片复制粘贴自动上传。

不支持网站上的图片复制后粘贴自动上传，这属于远程图片本地化功能。

实现方法：

1.修改文件\Public\common\assets\js\components\jtbc\jtbcEditor\jtbcEditor.js

V5.0.1.4及以后版本，修改文件位置：Public\common\assets\js\components\jtbc\jtbcFieldEditor\jtbcFieldEditor.js

添加一行

language:'zh-Hans',
images_upload_url: '/upload.php',//这一行是新添加的
setup: function(editor)

2.上传文件upload.php

上传位置：\Public\

直接拷贝以下代码自行新建upload.php文件
