"napped" and "allied"

[genosse27]

The change that alliances who are allied are no longer able to defend each other is a great success! We saw plenty active alliances and the bigger tags filled up with a few idles ones.

Now there is no real difference between being "napped" and "allied". To ally someone even has the disadvantage that your enemy can declare war to multiple alliances at once. A few things needs to be changed here.

I propose to be able to covert opert a "napped" planet.

Maybe we should even change more.
