Subject: [PATCH 1/2] Added optional params to get candlestick data

This is useful if someone wants to import data from earlier back in time.
Also removed the default 5m interval (regular parameters (callback) should not come after default ones).

This might break functionality for people who relied on the default interval.

 #### Get Kline/candlestick data for a symbol
+You can use the optional API parameters for getting historical candlesticks, these are useful if you want to import data from earlier back in time.
+Optional parameters: limit (max/default 500), startTime, endTime.
+
 ```javascript
-// Periods: 1m,3m,5m,15m,30m,1h,2h,4h,6h,8h,12h,1d,3d,1w,1M
+// Intervals: 1m,3m,5m,15m,30m,1h,2h,4h,6h,8h,12h,1d,3d,1w,1M
 binance.candlesticks("BNBBTC", "5m", function(ticks, symbol) {
 	console.log("candlesticks()", ticks);
 	let last_tick = ticks[ticks.length - 1];
 	let [time, open, high, low, close, volume, closeTime, assetVolume, trades, buyBaseVolume, buyAssetVolume, ignored] = last_tick;
 	console.log(symbol+" last close: "+close);
-});
+}, {limit: 500, endTime: 1514764800000});
