Quality of Life feature addition - Sort trader offerings by barter type (currency vs trade goods)

[MurkeyMirror]

You can currently buy stuff from the NPC traders with money or by trading certain items (Alyonka choclate bar/Phased array element/etc). For example, at Loyalty Level 1 with Ragman, you can trade an Alyonka chocolate bar for a VKBO army bag.

My suggestion is to add a way to filter these offerings from the NPC traders so you only see those offerings which you trade items for (that are not money, like Rubles/US Dollars/Euros). Maybe a button or some way to turn off this filter as well.

My idea is that you click the button and only see offerings which are trade goods only, excluding any that use currency. Maybe even add a filter for items only purchasable by Bitcoin/GP Coins.
