spine 动态换皮功能
前言：
cocos2dx 中spine 的换皮功能是一种静态的方法，也就是在创建 spine 动画的时候就必须将所有的皮肤全部加载，然后在代码中直接换皮，并且这种换皮是整体的切换，对于我们实际开发中这种方式是相当的不理想的。
注意：
本代码本人还只是简单的测试，如果还存在其它问题可以留言。
原理介绍：
对于spine动画而言动画的构成由 1、bone（骨骼）2、slot （槽）3、attachment（附件）组成，而动画中的图片资源都是通过附件来存储的。在spine的源文件由一个 xxx.atlas 文件 xxx.json 文件构成， xxx.atlas 文件其实就相当于我们的 plist 合图。 xxx.json 就是我们的动画描述文件，里面包含了。 bone、IK、slot、skin、animation、event 的描述。在解析后，所有图片附件都是元始于 skin 的，然后会挂载在 slot 下，也就是如果要换皮就需要替换 skin 和 slot 下对应的 attachment。
更新（2016/07/07）：
今天又研究了下，其实还可以再简化一些，原先是创建新的attachment 替换旧的，其实我们可以基于旧的attachment修改显示的纹理就行了，简化后代码见最后修改代码。
更新（2016/07/08）：
基于前面两个版本，因为换装一般都需要换来换去，那么如果能够保留原先的皮肤方便换回去还是很有必要的。因此本版本主要增加此类功能。
exmaple：
void* region = skeletonNode->replaceAttachmentImage("head", "head", Sprite::create("Images/head.png")->getSpriteFrame());
region = skeletonNode->replaceAttachmentByRegion("head", "head", region);

}slotName： 要替换皮肤附件所在slot名字
attachmentName： 要替换皮肤在 slot 上的 附件名字
frame： 要替换皮肤图片的 SpriteFrame，为了能够像spine一样利用合图的优势，这里使用的是SpriteFrame，同一个合图上的 SpriteFrame 会复用一个 spAtlasPage。
attachmentName2： 如果存在那种 slot 下有多个 切换用的 皮肤图片，而在slot下的名字都是同一个，那么就需要 传递这个名字默认为 nullptr
