Patch 1.1.2

Small patch to fix a couple of issues:

• Enemy submarines will position more aggressively

• Landed aircraft have the same visibility as their carrier

• Destroying enough of the landing craft to prevent the enemy taking the port now results in a successful port defence, even if the player subsequently retreats.

• Fixed bug causing player to get stuck in port after a port defence.

• Fixed a bug with using the Van Galen as flagship

• Fixed a bug causing ships to vanish from shipyard.
