Avoid JS errors if the console object doesn't exist

gistfile1.js

(function () {
	if (!window.console) {
		console = {};
	}
	console.log = console.log || function () {
	};
	console.warn = console.warn || function () {
	};
	console.error = console.error || function () {
	};
	console.info = console.info || function () {
	};
})();
