Avoid JavaScript errors with missing console object

// Ensures there will be no 'console is undefined' errors
window.console = window.console || (function(){
    var c = {}; c.log = c.warn = c.debug = c.info = c.error = c.time = c.dir = c.profile = c.clear = c.exception = c.trace = c.assert = function(){};
    return c;
})();
