[longomatch/redesign: 2/23] Update Project to use the new API

[Andoni Morales Alastruey <amorales src gnome org>]

commit 03801f33e20646a262b2aaedbde5c45d204b61de
Author: Andoni Morales Alastruey <ylatuya gmail com>
Date:   Sun Nov 21 15:38:42 2010 +0100

    Update Project to use the new API
    
    Projects are described with the ProjectDscription class.
    All the plays are now stored in a single array to make easier
    the management of categories.
