pytest-2.3.4: stabilization, more flexible selection via "-k expr"
===========================================================================

pytest-2.3.4 is a small stabilization release of the py.test tool
which offers uebersimple assertions, scalable fixture mechanisms
and deep customization for testing with Python.  This release
comes with the following fixes and features:

- make "-k" option accept an expressions the same as with "-m" so that one
  can write: -k "name1 or name2" etc.  This is a slight usage incompatibility
  if you used special syntax like "TestClass.test_method" which you now
  need to write as -k "TestClass and test_method" to match a certain
  method in a certain test class.  
- allow to dynamically define markers via
  item.keywords[...]=assignment integrating with "-m" option
- yielded test functions will now have autouse-fixtures active but 
  cannot accept fixtures as funcargs - it's anyway recommended to
  rather use the post-2.0 parametrize features instead of yield, see:
  http://pytest.org/latest/example/parametrize.html
- fix autouse-issue where autouse-fixtures would not be discovered
  if defined in a a/conftest.py file and tests in a/tests/test_some.py
- fix issue226 - LIFO ordering for fixture teardowns
- fix issue224 - invocations with >256 char arguments now work
- fix issue91 - add/discuss package/directory level setups in example
- fixes related to autouse discovery and calling

Thanks in particular to Thomas Waldmann for spotting and reporting issues.
