[Wien] Calculating x kram with intra-band contribution

In addition, it 'might' be that you also need more than one plasma 
frequency.  However, it has been a long time since I ran spin polarized 
optical calculation, so I don't remember for sure.


I think there were plamsa frequencies from running both "x joint -up" 
and "x joint -dn" from a spin polarized calculation:

I think it was possible to have multiple plasma frequencies from "x 
joint -up" (case.outputjointup) and "x joint -dn" (case.outputjointdn) 
based on:


https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16645.html


After using addjoint-updn, I think I might have had to combine all 
plasma frequencies from case.outputjointup and case.outputjointdn in 
case.inkram for "x kram" to run without error.
