[SQLObject] Development news

Testing news, to be precise. I fixed a number of warnings from py.test:

* I renamed classes TestXXX to SOTestXXX so that py.test doesn't
  recognize them as test classes;
* I converted yield tests that py.test declared obsolete to direct
  calls.

Now py.test doesn't produce any warnings.
