NodeJS compatibility breaks on the windows checks

[chrisramakers]

The exception handling part breaks NodeJS compatibility because checking for the presence of windows triggers a nodejs error. It's better to check if window is defined by checking it's type like below.

if(typeof(window) !== 'undefined') {
    // do stuff with window
}

I haven't checked the rest of the methods for nodejs compatiblity, this just popped up by just including the file in my nodejs project.
