Release notes v0.7.6.6

This took me quite a while, so for a week I stopped working on the civilizations to focus on optimizing the biggest bottleneck in the game. I think it's something that will benefit everyone. Enjoy!

Changes

• Huge performance improvement in rendering. The game should run better in all range of computers. This makes big planets more playable.

• Added simulation and rendering performance bars in the top left of the screen.

• Hide the current system's star when it visually crosses between the current planet and the player's camera.

Bug fixes

• Fixed creature dots not showing when the are is ice.
