[pygobject] Wrap four g_get_user_*_dir() functions

[Paul Pogonyshev <paulp src gnome org>]

commit fbed027845c24eb69a3325d6a5bc3c0aad12c4a8
Author: Paul Pogonyshev <pogonyshev gmx net>
Date:   Mon Apr 20 23:19:03 2009 +0300

    Wrap four g_get_user_*_dir() functions
    
    Wrap g_get_user_cache_dir(), g_get_user_config_dir(),
    g_get_user_data_dir(), g_get_user_special_dir() and the constants
    required for the latter.  Document all new functions and constants.
    (Bug #575999).
