document.write warnings

[martinklepsch]

Chrome recently (I think) introduced some warnings about using document.write() for script tags. Not sure if there are alternatives but the warnings are pretty verbose as they are.

@martinklepsch document.appendChild() is the preferred method so that the browser doesnt stop executing the current script.
