Unify permission names

Sometimes there is used edit and sometimes change, Django itself uses change.

Mind that there is a clear distinction in terminology: change means any act of updating data, whereas edit means the action of editing data in a (model) form.

Interesting theory. I can learn something new again and again ;-).

Well at least it would be consistent with the semantics of the editable attribute on ModelField.

Some things are definitely wrong:

# Create group type
create_group_type_predicate = has_person & (
    has_global_perm("core.create_grouptype") | has_object_perm("core.change_grouptype")
)
add_perm("core.create_grouptype", create_group_type_predicate)

should be

# Create group type
create_group_type_predicate = has_person & (
    has_global_perm("core.add_grouptype") | has_object_perm("core.add_grouptype")
)
add_perm("core.create_grouptype", create_group_type_predicate)
