[pymvpa] Mask in from_wizard generates no data.

[Thomas Nickson]

The mask is of type dtype=uint8 for the wizard and unspecified array for
the fmri.

I have loaded it from the original nifti and the fmri loader works fine. Is
it okay to use it like this? Or will I run in to trouble?

The mask for Dataset.from_wizard is just assembled by getImageData(MASK)
(which isn't very consistent) and it generates zeros. Is this correct?

For Dataset.from_wizard I tried loading it from the NIFTI but again I get
an error.

I think this is bug right?
