commit 9696f6dfd8a95548ebc98d7144d87fe00d1cf5ac
Author: Juan A. Suarez Romero <jasuarez igalia com>
Date:   Thu Jun 10 14:22:07 2010 +0200

    Add grl_init() function
    
    It initializes all stuff required in Grilo.
    
    More specifically:
    
      - It registers default metadata keys in the registry.
      - It registers grilo media types in glib type-system.
