Marco Bubke ada5ea1952 UnitTests: Fix names and disable slow tests by default 
Slow and very slow tests have now their own test category. We add SlowTest
for tests which are slower than ~5ms and VerySlowTest if they are slower
than ~100ms. They are disabled them by "-*SlowTest.*". If you have a faster
machine than most developers simply try lower values. The aim is that most
developers can execute the tests in under ~2s.

In the long run we should use dependency breaking and data sharing to
reduce the count of the slow tests.
