A bit more realism in caravan requests

[DarkAleks]

Today I got this caravan request:



And it wasn't first request that seemed quite wierd. So what do I suggest is making demanded items and reward in closer tech range. Basicly demanded items can't be lower than 1 tech level. Some examples:
1) If they offer glitterworld medicine, archotech parts and other items that are top tier and trade/ancient/quest only, they ask for spacer items or better.
2) If they offer spacer tech items (marine armors, bionics, etc.), they ask for industrial tech items or better.
3) If they offer high quality (master-legendary) industrial items, they ask for medieval tech or better.

It would make requests more meaningful. I mean, if they asked for 20 armor vests on screenshot or even 20 parka in fall/winter, it would make much more sense to me. It also creates some kind of upgrade ladder for items in your stockpile (that you haven't sold yet), promoting you to find and may be keep higher tech stuff to eventualy trade it for glitterworld items.
