Optimization Patch out

The optimization patch is finally out! I managed to break the game a lot when implementing the new optimization changes. So that's why it took me a week to finally release. I also had to do a lot of testing to make sure the game was stable so that took some time too.

I will now start working on 0.16 "Foundations of Civilization". Which will be focused around hunter/gatherer society gameplay. Very different from the current gameplay loop of the game.
