plist图片列表分割拆分器（修复输出图片错误的BUG）

网上的所有python版本代码，对于新版本的plist都是错误的！

本人做了修改，主要有：

1.更多旋转标签增加支持；

2.python的图片旋转函数调用错误，修改为transpose;

具体请复制以下代码保存为py文件，例如up.py，然后在plist和图片文件所在文件夹运行：up.py -plist c:\1.plist -png c:\1.png -dir c:\1\

注意：

1. 以上命令行“c:\1”文件夹提前创建才行。
2. 以上命令，需要提前安装好python环境，并安装Pillow才行（自己去搜索吧）；

看代码：

#!/usr/bin/env python
# coding=utf-8
# Python 2.7.10

"""
    This utility is used to parse plist file which is packed by Texture Packer to original images.
    usage:
        -plist specify the path of plist file(required parameter).
        -png specify the path of png file(required parameter).
        -dir specify a output directory(optional). By default, it will make a new directory named
             with plist filename in current directory to save images.
