Improve dissection process

[Prometheus3375]

Resolves #1.

TODO

• Implement move analyzer to verbosely describe moves made and generate appropriate steps.
• Implement method StateWithAllPositions.yield_solutions which is similar to solve, but it yields all done states with the least number of moves.
  • Method solve instead analyzes all solutions, takes the one with least number of steps and returns it with the steps.
• Add names for players in the main room. Distinguish between dissection player and ad clear ones.
  • Include these names in dissection steps similar to pass steps.
• Add tests for multiset?
