Mods as code

**What do you want to see?**
Mods that are CSX scripts rather than (or, in addition to) text files. The scripts would specify what raw data to load (or even define said data in the scripts themselves, if you really want), then manipulate it in various ways.

For instance, you could make a mod that says "Load Carrier Battles, but reduce the cost of all engines by half."

Dominions and Civilization have something like this, if I'm not mistaken.

**How would it help players?**
This would make modding a lot more flexible. You could actually combine mods if they are written as scripts, just by executing them in sequence.

**Alternatives**
Are there any other ways these benefits could be achieved? Heck if I know...
