Update the Gender Vendor

[Felis]

Adding in my opinion any mogstation/promotional outfits should be able to be salvaged as well. Back during times of less inventory, I rather stupidly accidentally tossed my amazon promo maid set, and after filing tickets was told it's not recoverable since it happened months ago. This is rather unacceptable for items we paid for, there has to be some record of it, and I should be able to recover this from the salvager.

This is about how the salvager NPC work. You need an achievement entry for it.
As an example, the Salvager NPC only sell the Garo gears if the set for it got completed for the achievement. He will not sell a single Garo gear from uncompleted sets.
