[grilo] core: Add "source-tags" property

[Juan A. Suarez Romero <jasuarez src gnome org>]

commit 5fd88084afe8a7469fc65abe1eff3b0a7ac5488f
Author: Bastien Nocera <hadess hadess net>
Date:   Mon Feb 10 12:37:40 2014 +0100

    core: Add "source-tags" property
    
    So that more information can be conveyed about the source's content
    to the front-end applications, such as:
    - the genre of the media (tv, cinema, radio, music, etc.)
    - the countries the media is relevant to
    - whether the media served is from the same machine, or from
      the local network
