1.11 Beta12 in experimental branch

Hi everyone I think we are nearing the end of the road for 1.11 beta. Unless a new bug report pops up, this could be regarded as a RC for 1.11. If anyone has any issue please report it back on the 1.11 thread, and i will look at it. Inside this release: Cleanup of country destruction code, Fixing a null reference / CTD error.
