Projects in the topic tests

While the python-based AppArmor utils (aa-logprof etc.) are much easier to understand and maintain than the old perl code, there are still some terribly long functions like parseprofiledata() in aa.py that are not too easy to understand. Also, using hasher() (a recursive array) as storage can have some strange side effects. Another problem is that test coverage isn't too good, especially for the bigger functions.
