Always Running Captain Commands

Makes your Captains' commands continue their progress even while the game isn't running! More precisely: this mod records the last real-world time every command was saved and then fast-forwards time when commands are loaded to catch up. If an ambush would've happened in the meantime, it will happen immediately--so be ready when you load your galaxy! For balancing: - Having control on when ambushes happen makes things easier. - Having all ambushes happen at the same time, even if they wouldn't have normally, makes things harder. - Catch-up time only happens a a 2/3 rate. Three hours with the computer off will replay as two hours as far as command progress is concerned. This way there's still a risk/reward advantage to managing real-time attention in the game.
