[glibmm] AppInfo: Add create_duplicate().

[Josà Alburquerque <jaalburqu src gnome org>]

commit 0dfeefb3cb604bdc6465155be7f5e333b435468e
Author: Josà Alburquerque <jaalburqu svn gnome org>
Date:   Tue Nov 6 15:41:59 2012 -0500

    AppInfo: Add create_duplicate().
    
    	* gio/src/appinfo.{hg,ccg}: Add the new method (which creates a
    	duplicate of the AppInfo).  Also, use gmmproc's optional parameter
    	functionality to wrap the launch_default_for_uri() method without the
    	optional AppLaunchContext parameter.
