'allowFuture' option or built-in Moment.js formatting

[philfreo]

Great library! Structured so much nicer than jquery-timeago for single-page js apps in terms of memory usage, etc.

Feature request: support the formatting of future dates like "in 2 months".

• Either something like the allowFuture option from jquery-timeago (although I think it should be on by default)
• Or a built-in way to use Moment.js fromNow for the duration formatting. I'm currently doing it this way:

$.fn.timeago.Constructor.prototype.timeAgoInWords = function(timeString) {
    return moment(timeString).fromNow();
};

My simple update to support future times as to update the TimeAgo.prototype.timeAgoInWords() function to the following:

    TimeAgo.prototype.timeAgoInWords = function(timeString) {
      var absolutTime;
      absolutTime = this.parse(timeString);
      
      if ( ( new Date().getTime() - absolutTime.getTime() ) > 0 ) {
        return "" + this.options.lang.prefixes.ago + (this.distanceOfTimeInWords(absolutTime)) + this.options.lang.suffix;
      } else {
        return this.options.lang.futurePrefix + this.options.lang.prefixes.ago + (this.distanceOfTimeInWords(absolutTime));
      }
    };

then in $.fn.timeago.defaults's "lang" key insert a line below "suffix":
futurePrefix: 'in ',
