A less overpowered version of nt1soc's TrainSpeedPlus.

Adds a more powerful nuclear fuel for vehicles + extended braking force research.

Enriched Rocket Fuel now has:
- an acceleration of 500% (originally 3000%)
- a top speed of 150% (originally 1500%),
- a fuel value of 8GW (originally 100GW), same as the uranium fuel cell used to craft it.

The extended braking force research modifier has been changed to match vanilla.
