[glib/osx-appinfo: 2/2] Implement GAppiInfo on OSX



commit 099dc4d0a8b4313e839aa14598bd07855fdd32c4
Author: TingPing <tingping tingping se>
Date:   Wed Mar 25 18:26:50 2015 -0400

    Implement GAppiInfo on OSX
    
    This is an implementation of most of GAppInfo using the OS X
    NSBundle APIs.
    
    Missing at this point are things that don't have equivalents
    in OS X, such as hidden desktop files, last-used, manual type
    associations, and g_app_info_get_all().
