Get New, Hot, Trending Links from Steemit

SteemDC is been created by @wehmoen, you can read about it here. I thought of adding features in this bot where you can get new, hot and trending links from Steemit.

The features SteemDC had were !steem, and I have added !hot, !created and !trending. It shows the Pending Payout, Total Votes, Posted Time and the Steemit Link.

To do this I am using Functions in Utils as

utils.getDiscussionByCreated(tag, limit) - Get limit number of created posts of the tag utils.getDiscussionByHot(tag, limit) - Get limit number of hot posts of the tag utils.getDiscussionByTrending(tag, limit) - Get limit number of trending posts of the tag

where the underlying function are send as a promise

    getDiscussionByCreated: function(tag, limit) {
        return new Promise(function (yes, no) {
            steem.api.getDiscussionsByCreated({tag: tag, limit: limit}, function (err, result) {
                if(err) no(err);
                yes(result);
            });
        })
    },
    getDiscussionsByHot: function(tag, limit) {
        return new Promise(function (yes, no) {
            steem.api.getDiscussionsByHot({tag: tag, limit: limit}, function (err, result) {
                if(err) no(err);
                yes(result);
            });
        })
    },
    getDiscussionsByTrending: function(tag, limit) {
        return new Promise(function (yes, no) {
            steem.api.getDiscussionsByTrending({tag: tag, limit: limit}, function (err, result) {
                if(err) no(err);
                yes(result);
            });
        })
    }

And for Posting to Discord I am first creating the PrintLink as shown below

 printLink: function(result) {
   let value = "Pending Payout : " + result.pending_payout_value;
   value += "\nTotal Votes : " + result.net_votes;
   value += "\nPosted Time : " + time_ago(new Date(result.created) - (1000 * 60));
  value += "\nhttps://steemit.com" + result.url;
  return value;
}

and post the printLink directly to Discord. However the functionality is greatly improved by @wehmoen and he uses embed function now which display it very nicely on Discord.
