Sale Completed Temporarily preventing Diamond Purchases

[Seiichi]

This is being done because there will be a Diamond sale in around 24 hours, and with the addition of new payment options there will likely be a flood of purchases before the sale.

I've left Services and Credits, so other things can be purchased, and I will re-enable the standard Platinum purchases with the sale tonight.

This is primarily being done to not overload myself with additional work and more math than I want to deal with when I re-imburse purchases who missed the sale by a few hours.
