add i18n support

[JLHwung]

It seems that bootgrid lacks the i18n support, at least on first glance. Currently the labels variable contains all the strings that need to be localized.

A sample of zh-CN localization (it works on 1.0.0) might be as follows:

(function ($) {
    "use strict";

    $.extend($.fn.bootgrid.Constructor.defaults.labels, {
        all: "全部",
        infos: "共{{ctx.total}}条记录，本页为{{ctx.start}}—{{ctx.end}}条记录",
        loading: "载入中……",
        noResults: "找不到记录！",
        refresh: "刷新",
        search: "搜索"
    });
})(jQuery);

I don't make pull request because one might need some extra designs on the code structure when formally taking locale into consideration. I will be grateful if bootgrid can add formal i18n support.

Easy hack.. For demo purpose.. Two variants 1) Modify core bootgrid template (dont pls, you know ) 2) make custom template (right way)

My solution -translate all - headers of table + default lang Custom template

templates: {  headerCell:   ...code... <a ...codedefault... data-i18n="grid.header.{{ctx.column.id}}">...code_default...

Using ajax - read docs, how parse & sending data (request...) Static table - i18n

lng.json "grid":{   "header":{    "col":{     "id": "ID"    }   }  }

I am using i18next.com
