[TIP] 2.3.1: regression and freebsd fixes

Did a quick 2.3.1 with some fixes:

- fix issue202 - regression with fixture functions/funcarg factories:  
  using "self" with class-level fixtures is now safe again and works as
  in 2.2.4.  Thanks to Eduard Schettino for the quick bug report.

- disable pexpect pytest self tests on Freebsd - thanks Koob for the 
  quick reporting

- fix/improve interactive docs with --markers

I am planning to do further quick regression-fixing minor 2.3.* releases
if neccessary - not going to announce each of them, though.

So make sure you have the newest version with e. g. "pip install -U pytest"
and keep the bug reports flowing :)


Changes between 2.3.0 and 2.3.1

- fix issue202 - fix regression: using "self" from fixture functions now
  works as expected (it's the same "self" instance that a test method
  which uses the fixture sees)

- skip pexpect using tests (test_pdb.py mostly) on freebsd* systems
  due to pexpect not supporting it properly (hanging)

- link to web pages from --markers output which provides help for
  pytest.mark.* usage.
