[gcompris/gcomprixogoo] Started the implementation of the load/save feature of anim.

[Bruno Coudoin <bcoudoin src gnome org>]

commit d257a967d71c07835ad08ec6c107d3022225c279
Author: Bruno Coudoin <bruno coudoin free fr>
Date:   Tue Oct 27 00:36:57 2009 +0100

    Started the implementation of the load/save feature of anim.
    For now, the save 'does something' but the load crashes GCompris.
