 * 
 * bluespring 修改1.6.4.1
 *	1.提供选项定制是否关闭提示框箭头 showArray
 * 	2.提供选项定制提示框是否在鼠标放上去的时刻出现还是一直出现 showOnMouseOver
 * 	3.提供选项定制input 效验错误样式
 * 
 * Quentin 修改
 * 	1. 无法全部去掉红色边框的bug   
 * 
 * matychen 修改
 * 	1.把css 中的errorform的padding-bottom改为margin-bottom ，如果不改，在checkbox的时候会遮挡。
 * 	2.当showOnMouseOver为true时。增加处理checkbox时，下面被占用，自己减少了top的高度，如果不减少top的高度，在checkbox的时候会遮挡。
 * 	3.修复了ie6的select遮挡div的bug
 * 	4.增加验证规则存放的属性名称
 * 	5.修改了ajax的发送到客户端的参数名称，返回值不用数组，直接用json对象。
 *		验证规则的名称validateError-->customAjaxRule
