Lua脚本自动生成APK包

上次用了纯bat写了个脚本生成APK包，感觉bat扩展性和语法差的令人发指，这次用lua重写了一个脚本
可以根据需要自行扩展了。
使用前tool path 还有 target path的前两个还是需要自己设置下。
一些小的函数 jit_file copy_file 我就不贴了 比较简单，用来luajit 和 拷贝。

-- Note:
-- This is used for Cocos2dx + Lua
-- This is a script to making .APK file for android platform
-- Make sure you have installed java, ant, android sdk, ndk, svn, jit
-- Also plz check and rewrite following paths before you use this script
-- Remarks:
-- The script will update your cocos engine directory and your Lua script which probably is Resources
-- then it should jit your Lua files , use ASMaker to encrypt your Lua-jit files
-- all files and resources will move to this folder proj.android/assets
-- finally it will make a .APK package with ANT
