Removed tests that have never been active.  #release-0.5.11

Said tests produce too much output on stderr, their noise swamps the
unittest framework signal.  Since they are not likely to be activated
until 2.2.0 at the earliest, just get rid of them.
Removed dead tests, some refactoring.  #release-0.5.11
Removed overly verbose instructions.  #release-0.5.11
