[Wien] intra-band contribution

[Karel Vyborny]

Dear Emami Seyyed Abbas,
for spin-polarised systems, you need to run the calculation twice. (Using 
x joint -up and x joint -dn etc.)  This way, you get permittivity for up 
and down separately and have to add them up at the end.

Yours sincerely,

KV
