Unstable update

Some neat things in this one -

• Rival factions now exist properly in the overworld. All of your political dealings will carry over from one colony to another so long as you're loading up the same overworld.

• There can now be rival dwarf factions. Steam post image

• Faction territories are per colony rather than per voxel. There's a toggle on the overworld screen to see them. Steam post image

• Claiming a faction's land for your colony will piss them off.

• Claiming land costs money. You'll need to make a profit to expand.

• Trade envoys will carry far less cash and goods. Don't assume you can be instantly rich by being a murder hobo.

• New corporate policy is that employees must pay for goods they consume. They aren't happy, but all dwarves will now pay when they eat or drink.
