Updated unit qualities for Norsca, changed Anark von Carstein's weapon

Fixed a bug that make some chaos knights model parts to be invisible

- Compatibilty with the mod "Vampire Army" by Adopotato and me.
- Compatibility with dryrain reskin (now all the units have custom texture and should not be affected by any reskins).
- Recolored golden part of the helmet which i have forgotten to do before release.
