Trader Visit + Currency

Trader Visit

A Trader would now visit your colony once you place a trading table. Currently you can only buy wood, and a pet monkey, but expect more in the future. Make sure to protect it from harm as broods, rebels would attack them if seen.

Gold Currency

I've also added a new structure called refinery (might change the name in future, but works for now). It'll convert ores/bars into gold, which acts as an in-game currency that you can use to buy goods from trader.

Lobby Tutorial

Also, Ive added a simple tutorial using the lobby station. Its a work in progress, but right now, it just shows an example of how to make a functioning base with proper oxygenated rooms and power.
