[2020] Rose Quartz now worth nothing

The update notes for this came in too late for the main notes, but should be coming with the first hotfix.

You can now use Powdered Rose Quartz to purchase material shipments from Quartermaster Zineb in the Sunspear Base. We wanted to preserve a way to make this useful for players outside of the Astral and Stellar weapons, that didn't involve straight silver from vendors.
