[1.0.1] Independent Powers

[Timothy001]

So I am seeing several issues with Independent Powers.

1. If an Independent Power is dispersed before you meet them by an AI, Their white borders can remain, and Settlements cannot be built on them, and cannot claim tiles that have them.
2. If you have met an IP, and anyone has started the befriend action, then anyone (You, or AI), disperses them, their banner remains, there units disappear. You can click on the banner, however, all actions are greyed out, and show 0 cost.
3. If you eliminate an AI, and they are the Suzerain of an IP, the IP reverts to a normal IP, but again they have no units, their banner remains, and again all actions are greyed out.

In the first 2 cases, the game should remove the IP, and release the tiles. In case 3, it should either remove or release the IP, so that they are available for another to befriend them.
