[gtk-mac-integration] Get GtkApplicationDelegate's application:openFile: handler to work at startup.

[John Ralls <jralls src gnome org>]

commit 866586a77970b4cb1095dda4951313ebc6a04907
Author: John Ralls <jralls ceridwen us>
Date:   Thu Mar 26 11:38:13 2015 +0900

    Get GtkApplicationDelegate's application:openFile: handler to work at startup.
    
    It fires off the signal before the main loop has started, so stash the
    URI in a static for applicationDidFinishLaunching to fire the signal.
