mask.c bugfix when restoring string containing whitespace.
More effective vectorizing in wpapsk-opencl (avoiding conversions in
inner loop).
More effective vectorizing in krb5pa-sha1-opencl (avoiding conversions in
inner loop).
Add a global bool "ForceScalar" in john.conf that turn off vectorizing
globally  in case you have a weak device that give "improper" hints for
our use (eg. if a side-effect of vectorizing is register spilling).
Add a --force-vector-width=N option (for debugging) and add support for
all sizes to the vectorized OpenCL formats.
