Leaders

**What do you want to see?**
Leaders you can recruit like in MOO2, GalCiv3, Stellaris, etc. that give sections of your empire various bonuses.

**How would it help players?**
Just another cool game mechanic for modders to play with!

**Alternatives**
Not really...

**Screenshots and mockups**
N/A

**Things to consider**
How should leaders be acquired? Purchased? Recruited? Built? Trained? Randomly appear?

Can they be transferred to another planet/ship/fleet once acquired?

We will need core code for leaders, and UI for them, and a mod to demonstrate how the're used, and art for them.
