GDesktopAppInfo: Add "filename" property for bindings

Browse Source 
GDesktopAppInfo violates the GObject rule that your C constructors
should just be thin wrappers around g_object_new().  While GKeyFile
isn't introspctable, this patch allows from JavaScript:

var app = new Gio.DesktopAppInfo({ filename: '/path/to/foo.desktop' });
