Title: Enforcing the dependency in migration

The migration step ```0001_initial``` of ```django_notify``` should be run before the step ```0007_auto__add_articlesubscription``` of ```wiki``` runs.
But in current code, as there is no dependency enforced, these two steps may be run in reverse order, which will cause an error in migrating if the migration was started after a ```syncdb``` operation on a empty database.
