Version 0.97 released
Trade Extension (TE_)
Trade Extension adds a very basic trade system to FTL. Trade goods come as 22 different augmentation type items. They can be bought and sold in trade events at each shop you visit. Different sectors supply and demand different commodities, transporting goods to other sectors nets profits. If you know where a certain cargo is in high demand and plan your route through the sectors accordingly you can make good scrap without endangering your ship. But be careful: Your Rebel pursues will not rest while you negotiate prices and load commodities. Trading takes time and makes the Rebel fleet catch up with you faster.
The trade system has is limited by what is possible with FTL events:
-Most important of all: Selling requires player corporation. When selling goods in the trade events, you need to sell the goods to the shop afterwards to get your full payment. There is no way to for modders to force you to do this, so cheating and breaking the trade system is possible every time you sell stuff in events. Just cooperate ok?

To remind you of this situation, you will get a subtle hint every time you sell trade goods in events:
[Reminder: Not selling off the goods at the shop breaks the trade system and means you are cheating.]
-Player has to be sure that he has space when buying, else he has to leave an argumentation behind or sell one to the shop and loose some money
-Right now, you can't buy and sell during the same event
-Profit can't be balanced according to difficulty, trading gives the same profit on easy and normal, offsetting the balancing a little
-Pirate sector shops seems to not use the trade events, cause for this is unknown
