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.
