    yelp-application: Handle command line args, GFile messes them up
    
    Ryan's work used G_APPLICATION_HANDLES_OPEN. Nice in theory, in that
    it does all the relative resolving for me. But GFile mangles things
    like ghelp URIs, so it's a no go. I hope startup notification is
    correct now. Double-check before release.
    
    Also added --version and --help, on the local instance.
