Testing the Preliminary Version of Gradient Ascent Pathfinder
Since the breadth-first search was just not fitting well with the ECS, I'm transitioning to the algorithm expressible directly as a ECS phase. The A* based algorithms can be implemented through ECS, but they will be limited to a single unit, since their diffusion map isn't really shareable.

I also had to introduce singleton entities just to express global actions, like the phase init and cleanup.

Currently I don't really need $scent_new double-buffering, but it helps debugging, since it wont introduce gradient bias, and it will be important with the dirichlet tessellated hierarchical version.
