Fixing Amazon SES, fatal error caused by bad connection

Hi Andris, I found a breaking bug and have a fix for it.

Bad connections cause a Fatal Error. And an uncaught error is thrown.

	$ node test.js

	events.js:72
	        throw er; // Unhandled 'error' event
	              ^
	Error: getaddrinfo ENOTFOUND
	    at errnoException (dns.js:37:11)
	    at Object.onanswer [as oncomplete] (dns.js:124:16)


Its actually a problem with `http.request()` made without a `req.on('error', handler)`. You can demo this by turning your internet connection off and running this code below (toggle the comment to see the fix).


	// TURN OFF YOUR INTERNET CONNECTION TO TEST
	var https = require('https');
	try{

		var req = https.request("https://google.com", function(){
			console.log(arguments);	
		})
		// UNCOMMENT THIS NEXT LINE TO FIX
		// req.on('error', function(e) { console.log('problem with request: ' + e.message); });
	}
	catch(e){
		console.log("Doesn't get caught");
	}

Please merge my changes below. :)

Great project, thankyou.
