Add custom item color in lists for enchanted weapons.

Any weapon with an enchantment (cursed, glow, holder, Colhorr weapon, enchant weapon etc.) will show up in a separate color in all lists. Currently this defaults to green and can be set by the client with other list colors (Options -> Colors -> List boxes -> Magic items).

Kod infrastructure still to come, this is just the client stuff (client number not incremented yet).
