mass Framework lang模块 v4

本次升级引进一些非常有用的方法，去掉一些用户也能简单实现的方法。详细如下：

• 字符串的blank, empty, toInt, toFloat方法， 它们被移到more/string模块中去。
• Object.forEach方法去掉，取而代之是Object.each，数组也增加一个叫each方法。each方法不同于forEach，它可以通过回调返回false中断迭代。
• 添加$.throttle与$.debounce，用于处理函数的调用频率。
• 精简一下$.dump的方法代码量。
• 添加stripTags，stripScripts，escapeHTML，unescapeHTML这四个在Prototype.js就赫赫有名的方法,专门用于处理用户输入输出。
• padRight与padLeft在实现就是一行的差异，现在padRight是在内部调用padLeft实现。
• 添加wbr字符串方法，对长字符进行换行，比如英文，数字在中文语句中不会断开，里面插入<wbr>就可以了。

2.任意字符中间都会插入wbr标签，对于过长的文本，会造成dom节点元素增多，占用浏览器资源。
