修改Cocos2d-X-3.2中的setup.py, 使其能用python3

Cocos2d-x的最新版是v3.2，下载地址为：http://cn.cocos2d-x.org/download/

在运行setup.py时，他会提示你安装python2.7,因为这个版本是他们"well tested"。

但是我电脑上已经安装了python3.3，又不想因为这事而卸载python3.3再重新安装python2.7, 于是就尝试修改setup.py文件。修改后的setup.py如下：

#!/usr/bin/python
#coding=utf-8

This script will install environment variables needed to by cocos2d-x. It will set these envrironment variables:
* COCOS_CONSOLE_ROOT: used to run cocos console tools, more information about cocos console tools please refer to
https://github.com/cocos2d/cocos2d-console
* NDK_ROOT: used to build android native codes
* ANDROID_SDK_ROOT: used to generate applicatoin on Android through commands
* ANT_ROOT: used to generate applicatoin on Android through commands
On Max OS X, when start a shell, it will read these files and execute commands in sequence:
~/.bash_profile
~/.bash_login
~/.profile
And it will read only one of them. So we will add environment variable in the same sequence.
Which means that
* add environment variables into ~/.bash_profile if it exists
* otherwise it will the add environment variables into ~/.bash_login if it exists
* otherwise it will the add environment variables into ~/.profile if it exists
Will create ~/.bash_profile when none of them exist, and add environment variables into it.

其实改的地方根本不多的，总的有3处：

1. 将import _winreg改成"import winreg"

2. 将raw_input改成"input"

3. 修改“_check_python_version()"使其返回True

经测试，这个setup.py运行已经可以完全正确了！至于该工程中的其他*.py文件未作测试，因为还没到执行的时候，相信如果要改的话，应该也不会多的，只要你愿意花时间。

我的测试平台是win7 x64, python3.3.5
