Should be able to set profile as init option, 'configure aws' behavior should be clearer/explicit

The current profile support seemed to present a bit of a chicken/egg problem, you need a valid project in order to call configure and set the profile, but you can't set the profile at the time you're creating the project. I've played around a bit and figured out that calling 'configure aws' outside of a project will set the profile globally, this just seems a bit confusing and at least should be expilcit in the cli's help
