[Wien] Bug / odd behavior: Can't change some of the session information

[Peter Blaha]

Hi,
the "session information" is meant as an information, and while one can 
change some options, this would not make sense and should not be done.

Eg. when you make a spin-polarized initialization and later on switch 
spin-polarization off, the calculations will crash. The same is true 
vice versa.

The "complex" setting is in more recent versions of WIEN2k done 
automatically based on the struct file. It checks if inversion is 
present in case.struct. However, if there is no struct file, this test 
yields "complex calculation" (obviously, inversion symmetry is not 
present).
I've now modified checkcomplex_lapw such that it returns nothing when 
the struct file is missing.

In essence: "session information" might give some information AFTER a 
calculation has been done, but is not meant to change this info.

Best regards
Peter Blaha
