[Wien] negative fermi energy

[Laurence Marks]

Energies in Wien2k almost always are relative energies, because the mean
potential is subtracted out. From your slab calculation you can find the
vacuum reference energy, then convert the Fermi energy into an absolute
number.

Note: in absolute units it has to be negative; think about it.
