Merge pull request #242 from hsogo/master

psychopy.visual.MovieStim.seek() fails when log=True
DOCS: bumped version number, updated changelogs, minor change to cedrus demo
BF: removed the incorrect scaling that was being applied to LMS color calibration

The use of scaling to the whitepoint of the monitor may be reinstated as an
option later, but can only be done as the rgb values are computed, not as part
of the conversion matrix itself.

A warning has been added for anyone trying to use LMS space in a stimulus
if their calibration was performed during the time that the error was in
place (version <1.76) although the number of users that this will affect
is expected to be extremely small.
ENH: sound.Server (subclass of pyo.Server) now successfully auto-shuts down
ENH: basic sound reproduction (wav files and numpy arrays) working from pyo
ENH: preferred sound libs can now be set in preferences>general>audio
Merge branch 'feature-pyo'
BF: PreferencesDlg handling string->list conversion better
BF: nxutils.pnpoly() can have problems, so add try-except

matplotlib 1.2.0-r1 on gentoo does have nxutils, but raised:
AttributeError: 'numpy.float64' object has no attribute 'frozen'

fix: try-except will now fall through to pure python.
long-term, might be better to figure out what is going on, might be a more
general issue for matplotlib 1.2.0-r1 (I use matplotlib 1.1.0)
