[Wien] zero DOS at fermi level

a) In older WIEN2k versions a DOS with just ONE k-point always resulted to zero DOS, because
    in the tetrahedron method this resembles only a set of delta-functions and the poles are
    never on your DOS-energy-grid.
b) In a new WIEN2k version, we switch automatically to a broadening scheme and your DOS should be finite,
    even with one k-point.
c) When changing the k-mesh, you should NEVER run    dstart again !!! I'ts a big waste of
    cpu-time.
    Save_lapw xxx
    x kgen  (generate a better mesh)
    run_lapw
          This uses the previously converged density and often after 3 cycles you are done.
d) No real idea why your DOS is zero, except: this is a big system and some previous steps
    (scf, x lapw2 -qtl, ...) might have stopped (memory, disk space,...)
