[Wien] lapw0 hang with mbj calculation for slab

[Peter Blaha]

For mBJ it is ALWAYS a good idea to use a larger IFFTfactor (complete 
cycle).

For a surface, case.in0_grr should not be present.

However, you need a file case.grr (normally prepared when case.in0_grr 
is present). This file (or the corresponding   avrg [(grad rho)/rho] 
value) should be taken from a corresponding bulk calculation.
