Give pirate transport and train mine slots

[Mephistoles]

They don't need mine slots. They don't have them already because they're transports, and regardless of what they are doing and who is after them, it shouldn't be so easy to get away in a transport. And if you understandably can't shoot the ring as you enter it, you can easily shoot the end one out, which gives you extra space.

The system is fine as it is.
