primary keys from character strings to integers, and makes corresponding code
changes.
This was prompted by database limitations discovered when trying to make
DocAlias use a m2m document field; with 255 long strings as primary keys for
Document and DocAlias this violated the MySQL database limitations.
Changing the primary keys to integers should also improve efficiency.
Due to the data migrations which create the new integer primary keys and adds
corresponding integer foreign keys matching the previous string foreign keys
in all tables having foreign keys to Document and DocAlias, some of these
migrations take a long time. The total set of migrations are expected to have
a runtime on the order of 2 hours.

in a database table:
- Added a GroupFeatures model to the group models, and removed the old
features.py
- Added a agenda type for future use in showing different group types on
different agendas.
- Renamed the group feature has_materials to has_nonsession_materials.
- Added API resources and admin support for the new tables.
- Added a Directorate (with reviews) group type as complement to
Directorate, to distinguish between directorates with and without reviews.
- Adjusted tests as needed.
- Updated the fixtures, and fixed the generate_fixtures script to include
the new AgendaTypeName objects.
There still exists about 70 instances of code comparing the group type
with a list of types; most of these should probably be replaced with new
features, instead, to make it possible to add new group types through the
database table, rather than having to edit the code. That was the purpose
of this refactoring from the start, but the presence of this large number
of comparisons of group type against lists of types defeats the goal until
we add appropriate features and replace the group type list comparisons.
