[Wien] orb moment

Of course any so-calculations for a spinpolarized case without  "initso" will
(most likely) be wrong.

The sequence must be:

runsp
save_lapw ...
initso  (with spin-pol case and "accept" struct file)
runsp -so

In many cases initso will reduce the symmetry (may even split some 
equivalent atoms and make them non-equivalent). Please be aware that
most likely there is a small bug in symmetso which may produce inconsistent
symmetry and lapwdm stops (but NOT with an error in atpar that it cannot
read the vectorso files !!!). The next release will have fixed this problem,
and as far as I know it concerns mainly hexagonal (non-orthogonal lattices)
with magnetization along x or y.
