[pymvpa] searchlight demo clarification

[Yaroslav Halchenko]

So, as John found out -- it was missing python-tk which is needed for
interactive pylab sessions, and which I guess was replaced with one of
the alternative backends at some point in the lifetime of the system ;-)

We might add an external check for python-tk in the cases of interactive
sessions...
