allow for line breaks in translations

[benjitastic]

My fix to allow line breaks (\n) in the translation js files was to introduce a line of code on line 159 of i18n.js:

    __: function () {
        var msg = this.translate(this.locale, arguments[0]);

        if (arguments.length > 1) {
            msg = vsprintf(msg, Array.prototype.slice.call(arguments, 1));
        }

        msg = msg.replace(/\n/g, "<br />"); //allow line breaks

        return msg;
    },

that means that an input like this:

{
"Never miss out, you can watch a replay.": "永远不会错过，\n您可观看重播",
}

outputs like this in express.js: in template file: <%- __("Never miss out, you can watch a replay.") %> actual code printed on page: 永远不会错过，<br />您可观看重播

Is there a better way to do this? Or any plan to allow for
output in future?
