Removed subfolder twitter_app and removed twitter token keys

Create a file keys.js with this content (it will be gitignored):

var twitter = require('ntwitter');
var twit = new twitter({
	consumer_key: '<consumer_key here>',
	consumer_secret: '<consumer_secret here>',
	access_token_key: 'access_token_key here>',
	access_token_secret: '<access_token_secret here>'
});
exports.keys = twit;
