#2822 disabling high/low goods warning colony+goods-specific doesn't work

[anonymissimus]

Messages of type
"There are now more than 270 units of cloth in your warehouse in Cloth/Rum"
possess a small x in their line in the turn report, which is supposed to disable this type of message for this colony. This doesn't work, the next time the cloth storage reaches the threshold the message comes again.
The message can only be disabled generally, all goods for all colonies, but that unfortunately also disables the more important "You warehouse in ... will exceed its capacity... " message.
