[gnome-calendar/ui-rewrite] build: add GcalSubscriber abstract class

[Erick Pérez Castellanos <erickpc src gnome org>]

commit dec8bcb3c9e3f3d88999972d42fdf39a15a7d0c0

    build: add GcalSubscriber abstract class
    
    GcalSubscriber abstract class is meant for handling the implementation
    of ECalDataModelSubscriber interface. The code in each vfunc implemented
    is the same for each view, then it makes sense to have a class holding
    these implementations and make every views descend from it. This class
    sits in the middle between GtkContainer and each of the views.
