[TIP] pytest-2.4.1: fix three regressions (of 2.4 compared to 2.3.5)

[holger krekel]

pytest-2.4.1 is a quick follow up release to fix three regressions
compared to 2.3.5 before they hit more people:

- When using parser.addoption() unicode arguments to the
  "type" keyword should also be converted to the respective types.
  thanks Floris Bruynooghe, @dnozay. (fixes issue360 and issue362)

- fix dotted filename completion when using argcomplete 
  thanks Anthon van der Neuth. (fixes issue361)

- fix regression when a 1-tuple ("arg",) is used for specifying
  parametrization (the values of the parametrization were passed
  nested in a tuple).  Thanks Donald Stufft.

- also merge doc typo fixes, thanks Andy Dirnberger

as usual, docs at http://pytest.org and upgrades via::

    pip install -U pytest

have fun and keep bug reports coming!
