global: InnoDB for MySQL
- INCOMPATIBLE Sets default MySQL storage engine to InnoDB (was MyISAM). Upgrade recipes for existing installations are provided. You may want to tune your MySQL server's InnoDB parameters for additional performance.
- Fixes models that have invalid foreign key types (affects collections, knowledge, oaiharvester, oauth2server).
- Fixes bug in access rule creation, caused by the fact that Python evaluates 0 to False.
- Kwalitee improvements.
- Fixes oauthclient test.
