nothing really -- just need to trigger tests
DOC: minor tune ups to corrcoef and WinnerMeasure docs
BF: CorrStability -- fix scaling and operation on arbitrary sa

This is old code which might get deprecated sooner than later. Was not tested
at all
RF: use 'space' instead of 'attr' for consistency with Anova etc
ENH: just minor tune ups to make code a bit more generalizable and concise
BF(TST): compatibility with numpy <= 1.4.1 -- use straight sorted on heterogeneous lists

Detected on nibotmi buildbot http://nipy.bic.berkeley.edu/builders/pymvpa-py2.6-osx-10.5-ppc/builds/153/steps/shell_6/logs/stdio
I left python3 logic previous (np.sort) since it is unlikely there would be elderly numpy
tested with python3 anyways, so minimized the change
Merge pull request #218 from yarikoptic/bf/corrstability

Bf/corrstability: rudimentary fixes and tests for CorrStability found in the codebase
BF(PY3): do no compare against threshold p until checking if not None

otherwise with python3 leads to crash (while with python2 just an empty match).
So took this also as opportunity to remove unneeded rebinding to p_thr complicating
analysis.
BF(PY3): ugly workaround for testing presence of tests

did not understand where eval issue comes from, but that is anyways
not really needed for this simple test, thus just allow to return
just a list of tests without their instantiation
BF: guarantee that enable_ca is always processed before disable_ca

as detected with failures on python3 our assumptions on
order were not always fulfilled and we have no control
over them.  So this provides a really ad-hoc solution explicitly
sorting all kwargs
Merge pull request #220 from yarikoptic/bf/py3-fixes

Bf/py3 fixes: none of them is elegant and underlying problem stinks with ancient code
BF: use actual path of the sphinx.ext module -- should fix FTBFS on trusty
BF: forgotten numpy import in cmdline helpers

a big warnings sign of need for tests :-/
BF: check if rdist_gen is still available while testing for rdist stability

User reported the crash

$> PYTHONPATH=$PWD python -c 'import mvpa2.support.scipy.stats'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "mvpa2/support/scipy/stats.py", line 62, in <module>
    if rdist.veccdf.nin == 1:
AttributeError: 'rdist_gen' object has no attribute 'veccdf'

but that code should not be executed on newer scipys (only on older ones with
misbehaving rdist), thus making sure that we do not even get there should resolve
this issue
DOC: few forgotten changelog entries
Changes to kick out 2.3.1 release
