Set editor script to windowed/scalable by default if no parameters specified

Its kind of opinionated but if a new comer doesn't know about the command line args or if you are launching via double click or something you get fullscreen when you probably want windowed with re-sizable.  I don't like adding the extra wierdness to the script which may confuse people.  I think this might be the lesser of 2 evils.  Like all my ideas don't feel afraid to shoot em down!
