I18n translate possible by override the validate.translate method

[huacnlee]

with #9

When the users want custom the validate messages, they can through override the validate.translate to done that.

var validate = require('parameter');

validate.translate = function() {
  var args = Array.prototype.slice.call(arguments);
  // Assume there have I18n.t method for convert language.
  return I18n.t.apply(this, args);
}

这里的 this 是指向谁呢？

[huacnlee]

t 呀？这么写有问题吗？还是我把 apply 理解错了？看起来能跑的呀。

[fengmk2]

没问题，这里应该传 util util.format.apply(util, args)

[huacnlee]

好了

[fengmk2]

这里也应该换成 validate 吧？validate.translate.apply(validate, args);

I'm agree #9, but I don't like #10 .

My opinion:

1. Localization in the parameter: paramter module buildin the localization, developers just need to set locale name.
2. Localization in the app: as 需要 I18n，所以返回验证信息里面的 message 不应该保函 key 的字符串 #9 said: message field exclude the key name, App can use gettext or koa-locales to localization.

But this MR use the third way, Localization in the app AND parameter module, I don't like it.
