Incomplete version for new empire placement stage on galaxy creation.
Still bugs on gradient descent. Some fixes, but need more debugging.
Semi-working. There is a small bug when multiple empires compete for the same update.
Simplified the algorithm, complexity was too high for little efficiency gain.
Modularized a little more.
Refactor of galaxy size handling.
Border exclusion zone for placing starting locations.
Fixed normal game code with new schema.
Small refactor to get the initial configuration for all empires.
Small fixes on zoom and distance for orbiters...
Added padding to world cammera. Useful in case we need to draw widgets outside the world.
Testing center on selection + enough padding to show widget.
Small refactor, eliminated many TODO in camera and decoupled movement from Game.
Added separate system to just move the camera enough to have space for an interface, both that and centering on click are now available.
