Another proof of concept, this time it's all about trade files.
I sorta' felt lied to when the game tutorial messages claimed that helping other characters will improve their attitude towards me so they'll be willing to sell me stuff cheaper... maybe I misunderstood what was meant but the feeling stuck anyway.
The purpose of this PoC is to demonstrate that not only is it possible to construct trade files so that NPCs with "friend" (green) attitude sell at lower prices but also that it's possible to make such adjustments to trader files automatically.

Off course all kinds of other adjustments would be possible, like increasing ammo supplies for traders or allowing more different items, maybe unique ones... I'm open to suggestions.
