Power Grid - Warp Engines

[alexanderson1993]

Develop the necessary things to make the warp engines work. This will involve a bit of stuff:

• [ ] We need to automatically create a battery for the warp engines to serve as the Warp Dynamo, with the option of having the engines run without the warp capacitor.
• [x] We need to create an ECS system for modeling battery/capacitor charging and discharging.
• [ ] We need to update the UI of the pilot screen to factor in activating the Warp Dynamo. Not sure what that's gonna look like yet, but it'll be something.
• [ ] There are probably autopilot considerations to include here.
• [ ] Limit the number of output connections from the warp dynamo to 1, so it can only be connected to a single power node.

This might be a monster, so it could be worth splitting it into multiple issues if deemed necessary.
